The screening mechanism of SNS website

I now often go to SNS is happy net and 5gme, feel that these two sites is precisely http://www.aliyun.com/zixun/aggregation/9105.html ">sns site spectrum of both ends."

Happy NET currently does not provide site search invitation function, you can only see their friends list of users dynamic. My friends in happy net are basically from my msn,gmail contact person turn over and invite, all "good friends" are my colleague, classmate or real world friend. Happy net lacks the mechanism of forming new circle of friends, according to this development is a strengthened version of MSN.

5gme is completely open, Keso, Liu Yan and other industry celebrities are estimated to be close to 4 digits in the number of friends. It's clear that they can't really interact with these "good friends", and ultimately these "good friends" are not fundamentally different from the readers on their blogs. According to this trend, 5GME is a strengthened version of the blog.

A position in the middle, allowing you to form a new circle, but there is a certain screening mechanism, perhaps a better choice.

Historically, a cohesive circle needs to establish a certain selection mechanism and organizational mechanism.

A common screening mechanism is based on origin, such as "upper-class" circles, where intermarriage is confined to the circle. This mechanism is too closed, eventually often enormous thin or produce a group of mentally retarded offspring.

More effective screening mechanisms are based on user behavior, such as Liangshan Juyi. Whether you are a dealers coach or a large rich man, the mountain first dry several cases, the name Yue "cast." Pass the test, then add as a friend.

With the screening mechanism, some organizational mechanisms are needed. The mechanism of Liangshan is very simple, in addition to Song Jiang, such as a few, all rely on force to speak, 108 of the ranks of the hero clearly.

How does SNS establish the screening mechanism? Typically, early Facebook, without an email account from a prestigious school or a big company, doesn't allow you to join in. 51.com has a similar filter based on user behavior, users need to do a few actions in front of the camera to verify the authenticity of their photos, this mechanism to help form the 51.com of the first bubble and bubble community status.

IT SNS who may be the first to solve the problem of screening mechanism? I am optimistic that Javaeye.robbin is my most admired personal webmaster, have ideas, understand technology, can implement, good operation. I was particularly impressed by the javaeye of community democracy and the screening mechanism, which I had already javaeye 1.5, wrote dozens of blogs, but so far did not have the right to vote. Without it, because my post is in the "water version", excluding the contribution value of the technical community. Javaeye once the introduction of SNS, I believe it will soon become the IT development circle user experience the best SNS.
