Web 2.0

After I read many of the story and news about Web 2.0, I believe this software is very powerful. This is like something must have! especially, I do most of the things everyday in my life on blogging, chatting, searching information, Bittorrent,Gmail, Google map or ebay... This web 2.0 can help many individuals satisfy their needs. I can see alot of good things about this Web 2.0. It is just like a new revolution for net users. this software is a good start to build up a community or network or business for people, but also danger that you might be the person to be harmed.
