the fact is [that] quantity does not imply quality.
The new algorithm is called Spamming-resistant Expertise Analysis and Ranking (SPEAR) and is based on the well-known information-retrieval algorithm called HITS that is used by search engines like Google to rank Web pages.

- Those people who first discover content that subsequently receives a lot of tagging can be identified as trend setters in a community
- followers find useful content later and tag it because it is already popular
- people who identify a topic that grows in importance and use it to point to their own stuff

Usability Study: Men Need Speed - web usability criteria show gender differences

The importance of download speed, for most Web users, has long been established (King 2008). Fast response times foster higher flow states (Skadberg & Kimmel 2004), higher conversion rates (Akamai 2007), higher perceived trustworthiness (Nielsen 1999), and lower user frustration (Ceaparu et al. 2004). But, previous research has also found that differences in gender, age and computer self-efficacy can moderate user priorities. This article explores the differences among men and women in their desire for speed.

Technology Review: The Evolution of Retweeting

In the 140-character limited ecosystem of Twitter, users have evolved a language of their own, figuring out creative ways to filter the sometimes overwhelming stream of Twitter posts. Now, Twitter has announced that a user-generated communication technique called retweeting--reposting someone else's message, similar to quoting--will be formally incorporated into Twitter.

Twitter has incorporated other user-generated linguistic tools, such as using a hash symbol in front of a word to make it easily searchable
Another common technique is typing @ in front of a username to reply directly
12 more annotations...
- These linguistic tools have even trickled into other social media environments, including YouTube, Flickr, Facebook, and blogs.
- The most common scheme for a retweet involves prefacing the post with the letters "RT," then the @ symbol, and the username of the person being quoted.
- The retweet rebroadcasts the information to a new set of followers, who see the retweet and have the option of retweeting themselves. In this way, ideas, links, and other information can be distributed--and tracked--fairly quickly.
- witter announced that it will soon implement a button that will let users automatically repost someone else's tweet.
- Adding commentary is a huge element to why people retweet.
- Instead of just replying privately to a person with an opinion, by retweeting and adding a comment, users can target a larger audience, sharing their opinions and inviting others to do the same, she says.
- Boyd found that 11 percent of the retweets examined contained commentary.
- "Retweeting is primarily used by the geeks and news folks," she says. "What's really starting to hit [Twitter] in large numbers... are those involved with the pop culture."
- Users often employ retweets to provide context in conversation, says Susan Herring, a professor of information science and linguistics at Indiana University and editor in chief of the Language@Internet journal.
- A retweet plus a comment is a conversation. A retweet alone could be an endorsement, but it's a stretch to view an exchange of endorsements as a conversation.
- Retweets are not just of interest to users but also are valuable to companies and researchers who strive to keep track of how ideas spread.
- "People will continue to repurpose Twitter to meet their needs,"

Firms are buried under data, a lot of which they don't need

- The lack of having a data strategy is driving companies to collect more and more data needlessly
- every piece collected should help answer one of two questions: what is a customer's value, or what are a customer's needs. "Anything outside of those two objectives may have a legitimate reason to be collected, but more likely than not it's superfluous
- Put yourself in customers' shoes and ask whether you'd want more and more information about yourself available to be misused.

兩岸網路產業發展的差異性…@三十而慄-网络、财经、法律、职场、全球化趋势

人口僅有2,300多萬人口，因此在先天的市場之上，規模已經決定了一切
中國內地的狀況，則呈現完全不同的發展態勢，因為幅員廣闊，人口眾多，市場之大無邊無際，加上產業的開放、發展時間較短，因此相對的根基上較為薄弱，在這兩者因素的交錯之下，又因為面臨跟時間、競爭對手賽跑的趨勢之下，發展出所謂的圈地策略，先求有再加強，因為投入時間較短，還沒有足夠的累積性，所以產品粗糙一點無所謂，而用戶其實也沒有這方面的認知，

- 大規模的操作手法也是因應大市場的重要策略，先搶先贏的佔地、搶人頭手法大行其道，讓用戶先對其品牌有印象並進一步認同，因此在時間的考量之下，產品的完整度、精密度不是最首位的考量，反而能夠搶先上市成了行銷上的重要指標
- 先天市場性不足的台灣，意識到了追求流量的不切實際，轉而力求專業、專精，比方說：提升檢索、搜尋的更高效率、提昇資訊的再利用價值…等

Backreaction: Paper Zapping

A nice quote from Strategic Reading, Ontologies, and the Future of Scientific Publishing, by Allen H. Renear and Carole L. Palmer (Science, 14 August 2009, p.829), on how scientists make use of the literature:

s scientists search and browse, they are making queries and selecting information in much tighter iterations and with many different kinds of objectives in mind, almost as if they were playing a fast-paced video game
Just as the aim of channel surfing is not to find a program to watch, the goal of literature surfing, is not to find an article to read, but rather to find, assess, and exploit a range of information by scanning portions of many articles

InternetWatch friendfeed

First, let's put the size of the two sites in context. Facebook ranked #2 among All Categories of websites last week (behind Google) and was #1 among Social Networks and Forums. Friendfeed by contrast ranked #9010 among All Categories and #421 among Social Networks and Forums.
A comparison with Google and Twitter's downstream traffic reveals, as one might expect, that Friendfeed's clickstream profile is much more similar to Twitter than to Google.

- Friendfeed is currently receiving much more traffic from Facebook than it sends back. Last week, the top referrer of visits to Friedfeed was Google, accounting for 21.03% of upstream visits followed by Facebook with 9.60% of visits. Looking downstream, Facebook ranked #4, receiving only 4.69% of Friendfeed's downstream visits, behind Twitter, Google and Picassa Web Albums.
