The Spirit of Sharing under Web2.0 Thinking

In the article "A Few Thoughts on Optimizing Blog Tags," I mentioned that I wanted to write an article about DIG and WEB 2.0. The idea came from a question asked by "Xing" on Shouke.net, who wanted to know how to get more people to DIG others' bookmarks. I've been thinking about it off and on these days. After experimenting with the "public subscription-widget" function on Zhuaxia today, I drafted this article. Below, I have organized my thoughts to share with everyone.
