My friends and I build a website for scientists to discover & share journal articles that are worth reading, to discuss scientific ideas that are worth spreading, and to connect with people who share similar interests: http://www.pubup.org/ . Please let me know what you think of the idea and the website. Thanks!
The idea is great, but just so you know... my experience in academia (anecdotal) suggests that Mendeley already has a pretty substantial lead: http://www.mendeley.com/
Me and my friend use facebook, twitter, and (mostly) have appoinment to share interesting paper to read. Discussing paper offline are the reason why we meet. Haha..
I'm completely open to an alternative service (or even a complementary one). So... I guess what I'm trying to say: Give me, one of your intended customers, a compelling use scenario or value-add proposition that might compel me to switch.
