Favorite Web2.0 services. [weekly link post]

According to Wikipedia, web 2.0 is a trend in web technology which aim to facilitate creativity, collaboration and sharing among users. Blog itself is a part of web 2.0 movements.

I like the web 2.0 workplace entry on UADDit (They visited web 2.0 companies and show pictures of companies' insides). I heavily use most of the web 2.0 companies' services they visited. These services are very famous, but in case you have not used them, I put links to the web 2.0 services (I am personally using following services) . Check them out.
