xlvector – Recommender System

http://www.readwriteweb.com/archives/facebook_unveils_one_of_the_historys_most_powerful.php

Important parts:

Facebook will now recommend that new users sign up for updates from (“Like”) publishers with high reader engagement and subscribed-to by people demographically similar to themselves.
给新注册的用户推荐热门的用户和具有相同社会属性的朋友，这一点twitter似乎也做过了，注册的时候可以选择几个好友。

The Facebook vs. Google battle could become a fight between Recommendation and Search.
这话太激动人心了，推荐不至于和搜索走到对立面上去吧。

Recommendation-geeks have argued that recommendation may someday become bigger, more important and more lucrative than search. Recommendation is like a smarter, pre-emptive search before you even thought to search for anything.
我一直觉得推荐和搜索满足了用户两种不同的需求，缺一不可，这两个市场并不矛盾，可以携手发展。

It’s too bad this had to happen under a proprietary platform with privacy problems.
隐私！！个性化永远绕不去的坎。
