I drop a comment when I like a article on a site or if I have something to contribute to the conversation. It is triggered by the passion displayed in the article I browsed. And after this article 发表帖子 - 综合讨论 - 旧梦吧. I was actually moved enough to write a commenta response :-P I actually do have 2 questions for you if it's allright. Is it only me or do some of the responses appear as if they are written by brain dead people? :-P And, if you are writing at other online social sites, I'd like to follow you. Could you make a list all of your public pages like your twitter feed, Facebook page or linkedin profile?
