Understanding Users of Social Networks — HBS Working Knowledge

"I just wondered why people spend so much time on these sites; what do they do?"

The biggest discovery: pictures. "People just love to look at pictures," says Piskorski. "That's the killer app of all online social networks. Seventy percent of all actions are related to viewing pictures or viewing other people's profiles."

Piskorski has also found deep gender differences in the use of sites.

Piskorski says these findings do not hold for one network: Twitter...."Only the people who are willing to put themselves out there publicly in words to people who they may not know will use Twitter.

But the remarkable finding was the gender dynamics. According to the research, there are more women on Twitter than men, women tweet about the same rate as men, but men's tweets are followed by both sexes much more than expected by chance.

"Women actually say things, guys give references to other things." But even accounting for these differences, the researchers still saw differences between how men and women are followed, perhaps pointing to a fundamental representation of the role of men and women in society.

why doesn't MySpace get the attention it deserves?

The fascinating answer, acquired by studying a dataset of 100,000 MySpace users, is that they largely populate smaller cities and communities in the south and central parts of the country.

learning networks communities Connectivism language social

I think it suits perfectly to say that the person-to-person network tied by common reading is a learning network. However, without other corroboration, I would not like to call it a learning community because for that I would like to see actual interpersonal ties.
I think it becomes quite confusing if we mix people and resources as nodes,

- strong, weak and new ties in a network structure are important.
  
  Sometimes a community perspective tends to focus too much on the core of a community and therefore develop a more inwards perspective on community learning
- I'm pretty sure the ideas we're generating about learning networks and learning communities can and will pick up from and translate back to offline learning.

Are Your Friends Making You Fat? - NYTimes.com

I heard precisely the same thing from many of Pentland’s peers. They have all long suspected that human behavior is widely contagious; they just don’t think Christakis and Fowler have proved their case.

networks legitimate peripheral participation

People who study networks use shorthand for a persistent phenomenon: the 100:10:1 rule. In a group of a hundred people, only one person is likely to initiate dialogue. Ten people will comment, argue, question, provide examples and stoke discussion around the one individual’s seed. A hundred people learn from observing and applying what they silently learn from the others. When social networking theory was immature, silent partners were denigrated as lurkers and losers. But without silent observers, everyone would be talking at once and chaos would ensue.

In places where passion and emotion should not prevail – when building bridges, say, or launching space shuttles – groups should not prevail. In places where passion should prevail and is even an asset – in team sports, in family bonding - groups should prevail.
we are asking fundamentally what the role of our educational system should be. Should it be to foster an emotional attachment to a group,

- There is no shortage of people wanting schooling to fulfill not only a learning but also a socialization function
- This, then, is where the teaching becomes less a matter of cognitive function and more a matter of indoctrination.
- But in matters affecting economics and finance, environment, government and nations, we can no longer afford group-based tribalism.

Groups Vs Networks: The Class Struggle Continues ~ Stephen's Web ~ by Stephen Downes

downes groups networks

And it seems to me that networks offers that middle way. Networks offers that path that isn't the individual and isn't the group, doesn't force you to choose between the individual and the group. I am saying this because as soon as I came up with this "groups versus networks" people are looking at that and saying, "Well what's the middle way with that?" And I thought, "Wait a sec, this is the middle way.
Groups are about nature, they're about quality, they're about mass. They're about number.

A network, by contrast, is an association â I use that word very precisely â an association of entities or members where this association is facilitated or created by a set of connections between those entities.
20 more annotations...
- Interestingly, democracy is a group phenomenon. Democracy is a bunch of people who are relevantly the same,
- a network is like an ecosystem where there is no requirement that all the entities be the same, where the nature of the entity isn't specifically relevant, where the number of entities isn't specifically relevant.
- so he brings the concept of universal law that applies equally and the same to everybody in Athens. And it's funny how that has survived as an essential and elemental concept in learning today.
- I want testing to be done by at random by comments from your peers and other people and strangers based on no criteria whatsoever and applied unequally and unfairly.
  
  And people say, "Well, why would you want that?"
  
  And I said, "Well, that's the way the world works."
  
  But the point of that remark is to try to pull apart this idea of universality, everything being the same and learning. Do we need, as is suggested, do we need the iron hand of justice in our classrooms?
- And the United States, like groups, constitutes a melting pot. In Canada, we were all taught, is a salad bowl
- was it indoctrination or were they right? And after many years, I've come to the conclusion they were right. And so there is this idea of the network, there is this idea of distinctness and diversity in an environment where people are encouraged not to be the same, but to be different.
- what defines these things is the set of connections between the individuals and not the content of what's going out.
- Groups require coordination. They require a leadership or a leader which is why we get all of this stuff on leadership. It's the funniest thing, all these things on leadership, because I read these and it's like everybody needs to be a leader, but my experience of groups is usually one leader and a bunch of followers
- I look at groups as somebody else's leadership, somebody else I'm responsible to. I have to follow his or her vision, as being "responsible" assumes that I'm under somebody. People picture groups, but they don't picture them in terms of their actual role in the group. They picture them in terms of the role they would like to play in the group. It's a philosophy of aspiration rather than a philosophy of reality.
- the person who came up with the concept of the vision statement should be thrown out the window.
- Learning design, where the learning is organized, sliced, diced, flaked and formed and you follow in a row or you're not a learner.
- Networks, by contrast, require autonomy. That is to say each individual in a network operates independently. That does not mean they operate alone. What that does mean is â because remember, it's a network, you're connected, you talk to people, they talk to you â it means you define your vision. It means you define what's going to be important to you, your values and interests.
- Interaction in a network isn't about leaders and followers. It's about, as I say here, a mutual exchange of value.
- Oh, but we're in this institutional environment. We have to do what we're told."
  
  And my response is, "Who said so?" I mean, why? I mean the worst thing they could do is fire you and then you'd be free,
- But if you read and listen to all this pedagogical theory, it's like, "gee, if we don't take them by the hand and lead them through this, they'll be hopelessly lost and they'll never learn anything at all."
- That's our theory of learning. If somebody wants to come in and listen, we stop them.
- It's the long tail and all of these individuals of just two or three links, but the thing is, you know, this message is being given to us mostly by people who are in what I call the big spike, the A-listers. And they're sitting there saying, "Look at this power law. We're out here. We're making a mint."
  
  But the thing is, that power law of distribution is more characteristic of groups than it is of networks. A network, properly constructed, will not see that configuration where two percent of all the people own 80 percent of all the wealth. Rather, it becomes more distributed â the more evenly you distribute your links, the more evenly you distribute your wealth.
- the knowledge of groups is limited by the capacity of the leader
- Those of you who are into learning theory think more about transaction theory, of communication theory. It goes from here to here to here to here. And consequently, that limits the type of knowledge that can be created and communicated.
- But in a network, the knowledge is emergent.

actors
these basic properties of social networks have very important consequences.
10 more annotations...
- Individuals may be "sources" of ties, "sinks" (actors that
  receive ties,
  but don't send them), or both. These kinds of very basic differences among actors immediate connections may be
  critical in explaining how they view the world, and how the world views them. The number and kinds of ties that
  actors have are a basis for similarity or dissimilarity to other actors -- and hence to possible
  differentiation and
  stratification.
- The distances among actors in a network may be an important macro-characteristic of the network as a whole.
  Where distances are great, it may take a long time for information to diffuse across a population. It may also
  be that some actors are quite unaware of, and influenced by others -- even if they are technically reachable, the
  costs may be too high to conduct exchanges.
- A trail between two actors is any walk
  that includes a given relation no more than once
- All trails are walks, but not all walks are trails.
- A path is a walk in which each other actor and each other relation in the graph may be used at most
  one time.
- here we have measures of the strengths of ties (e.g. the dollar volume of
  trade between two nations), the "distance" between two actors is
  defined as the strength of the weakest path between them.
- The multiplicative nearness transformation divides the distance by the
  largest possible distance between two actors.
- The "flow" approach suggests that the strength of my tie to you is no stronger
  than the weakest link in the chain of connections, where weakness means a lack of alternatives.
- It is also logically close to the idea that the number of pathways, not their length may be important in connecting
  people
- he local connections of actors are important for understanding the social behavior of the whole population,
  as well as for understanding each individual.
