If you like science fiction and you’d like to quit smoking, this is the site for you: www.quitdoingit.com.

A part from the good video interface and the sarcastic domain name, I can't say I found the experience cool and engaging enough to convince me to quit smoking (maybe because I don't smoke? ;-) but as usual I appreciate the effort of using the Web to deliver socially relevant messages.

Also, if you click around, you'll find a sort of Web 2.0 program called FixNixer that should help you quit smoking in 21 days...
