“Freemium” 是当前最适合互联网的经营方式

Evernote是一家互联网公司，仅仅成立了一年半。它的服务是让用户把Evernote当作手中的小纸条，有任何事情都可以通过电脑终端、手提电话等途径记录在Evernote里面。可以是文字、WORD文档、PPT、PDF等任何你可能想到的收录介质。Evernote可以让用户注册后免费使用，但遇到某种高级服务例如拓展自己的空间、上传比较特殊的文件格式等。就是这种简单的服务让Evernote在2009年7月单月的收入已经达到将近8万美元。而这仅仅是一个拥有140万用户的小网站，付费会员只有百分之二。这是一次Freemium模式成功的经典案例。

“Feemium”这种模式虽然刚起步不久，但是已经展现出了它巨大的潜力。并且通过分析Freemium的特性，我们发现它十分的适合互联网的发展

“We could easily preview all the images, place them in our program to make sure they worked, purchase them online and download the high-resolution versions — all in seconds,” Greer added. “We had a script that called for 4 to 5 voices. Rather than hiring local voice talent — for $250 to $500 per hour — we searched the Internet for high-quality voices that we could afford. We found several sites offering various forms of narration or voice-overs. We selected www.voices.com. In less than one minute, we created an account, posted our requirements and solicited bids. Within five minutes, we had 10 to 15 ‘applicants’ ” — charging 10 percent of what Greer would have paid live talent.

“Best part,” he said, “within minutes we had sample reads, which could be placed into our film to see if the voices fit. We selected our finalists, wrote them with more specific instructions and within hours had the final read delivered to us via MP3 files over the Web. We could get any accent or ethnicity we wanted. For music, we used a site called www.audiojungle.net,” where he could sample thousands of cuts of music and sound effects with the click of a mouse, and then buy them for pennies.

But here is the broader context in which I assess all this: My own foreign policy thinking since 9/11 has been based on four pillars:

1. The Warren Buffett principle: Everything I’ve ever gotten in life is largely due to the fact that I was born in this country, America, at this time with these opportunities for its citizens. It is the primary obligation of our generation to turn over a similar America to our kids.

2. Many big bad things happen in the world without America, but not a lot of big good things. If we become weak and enfeebled by economic decline and debt, as we slowly are, America may not be able to play its historic stabilizing role in the world. If you didn’t like a world of too-strong-America, you will really not like a world of too-weak-America — where China, Russia and Iran set more of the rules.

3. The context within which people live their lives shapes everything — from their political outlook to their religious one. The reason there are so many frustrated and angry people in the Arab-Muslim world, lashing out first at their own governments and secondarily at us — and volunteering for “martyrdom” — is because of the context within which they live their lives. That was best summarized by the U.N.’s Arab Human Development reports as a context dominated by three deficits: a deficit of freedom, a deficit of education and a deficit of women’s empowerment. The reason India, with the world’s second-largest population of Muslims, has a thriving Muslim minority (albeit with grievances but with no prisoners in Guantánamo Bay) is because of the context of pluralism and democracy it has built at home.

4. One of the main reasons the Arab-Muslim world has been so resistant to internally driven political reform is because vast oil reserves allow its regimes to become permanently ensconced in power, by just capturing the oil tap, and then using the money to fund vast security and intelligence networks that quash any popular movement. Look at Iran.

From a learning standpoint, there is proof emerging that using Twitter builds intelligence. A study revealed these benefits:

All of the study participants were new to Twitter and had not previously used it or any similar microblogging service…..In a relatively short period of time, the participants formed quite sophisticated peer networks…..Peer support became a key feature of this student network, with activity rising just prior to assessment deadlines or during revision for exams. Content analysis of the messages indicated clear evidence of the emergence of personal learning networks…..Twitter is also very attractive as a data collection tool for assessing and recording the student experience, with a wide range of free and increasingly sophisticated online analysis tools available.

There aren’t many tech products I would consider myself dedicated to. I change browsers at least weekly, keep at least one Mac, one Windows machine and one Linux PC around at all times and a two-year cell phone commitment can seem like a prison sentence by month six.

I’m also not the kind of guy who gives glowing reviews, everything is usually tempered with a mix of good and bad, an attempt to find balance and deeper understanding.

But there is at least one service that I am truly grateful for, Diigo.

You see, when most people think of social bookmarking, they think of Delicious due to its popularity. However, for me and my specific needs, Diigo has been a savior, providing a much-needed service that’s simple, reliable and attractive.

If I’m going to rave about any service I use, Diigo would be it and as the U.S. celebrates Thanksgiving, I want to celebrate one of my favorite tech services and how much it has helped me.

因为我们肠子里的消化 并不能消化寡糖，反而会被肠道中细菌所利用，故不会在体内囤积，因此不会发胖，就形成了所谓的健康饮料了，其保健情形列如下。

1.可取代精致糖使用

一般的糖是有很高的热量，不适合肥胖或欲减肥者或糖尿病者使用。寡糖的甜度约为蔗糖的20~70%，口感与蔗糖近似，但不像蔗糖一般会被口腔中的细菌利用，产生酸性物质侵蚀牙齿，因此不会造成蛀牙。一般言，寡糖每克只产生0～2.5大卡的热量，也不会对血糖值与胰岛素的分泌有任何的影响，因此也被当成低热量或糖尿病人的甜味剂使用。蔗糖会促成中性脂肪的上升，寡糖却有促进血脂肪下降的效果。

2.调整肠道有益菌丛生态

果寡糖可作为体内双叉 菌---比菲德氏（Bifidus）菌等有益菌生长繁殖的营养份，而压抑有害菌种的生存空间，促成肠道有益菌丛生态健全。如此可增加营养的吸收效率，并减少肠道有害毒素的产出，而维持免疫机能、减少肠道发生恶性肿瘤的危险、延缓老化。故果寡糖和乳酸菌、膳食纤维等物质一样，都是整肠、体内环保、促进正常排便的好帮手。

3.降低血脂肪含量

许多研究都指出果寡糖对血胆固醇与中性脂肪的下降有帮助，果寡糖和膳食纤维一样，也有助於血中胆固醇的控制，其生理机制与膳食纤维类似，也是能与胆酸、胆盐结合而将其排除於体外，防止再吸收，体内就会促进胆固醇在肝脏进行氧化作用产生胆酸，降低血胆固醇浓度。

4.提高矿物质的吸收率
