Web 2.0 tools

Well, I enjoy using those tools. The one I found very useful and I had not use before is " Del.icio.uz" and it is very useful to me. The others like Google Doc is very helpful to me. Also I use a lot Picasa for editing my picture, creating web albums to share with my friends. Google earth and Google map are useful too. Recently I used Flickr to search photos and I found a lot of good photos. I use facebook as a social networking and found a lot of old friends there. Since I am not a music friend so I seldom use those music tools.
