The two entries posted earlier were motivated by a few positive comments received from friends I forwarded the links to. I posted them here for people who might be interested but are not on my forward mail list.
I still haven’t decided whether keeping a blog is compatible with my goals, and if yes, for whom do I want to write. Should I send targeted emails sprinkled with personalized comments to friends who I think might be interested in a certain topics , or should I post them here for anyone cares enough to read? Perhaps I should just blog whenever I feel like it (like DDY) and not trying to figure out what I want to keep a blog for (keeping in touch with friends, writing for a broader audience, for thoughts, reflections, or diary, etc.). After all, blog entries don’t have to be consistent. They don’t even need to be good as long as I don’t mind.

My reasons:(1) thoughts come fast, go even faster (catch them)(2) keeping in touch with friends (cost saving)(3) motivation of promoting "self-selection".
Feng – not sure if I understand what (3) means.
第三点：博客还有一点理由是针对陌生人的，由于人们有自我的选择的能力，所以只要有兴趣，爱好，想法，相同。甚至想法不同，但有同一种思考的过程或者困惑，人们就会参考一些类似群体的想法。就像我，特别喜欢听一些人讨论各种事情，也能从中学到很多东西。回想过去的几年，那些一开始陌生的人，由于这样的一种形式和习惯，现在都成了很好的朋友。特别怀念大学一年级的那段时光，一群陌生的男孩，一起在一个独立的寝室，在不是很大的空间，讨论着各自的观点。那时有那样的机会，现在这种机会越来越少，很多原因就是人们在长大的过程中，慢慢的开始变得理智和保守，这是有它的道理的，也是必要的。http://fengzhou0529.spaces.live.com/blog/cns!B3B24F0420A298E1!1140.entry
