Imagine Facebook going into Bioinformatics - getting hundreds of millions of users collaborating with friends to solve real-world problems. What type of projects can grow on such a large social network of individuals who mostly don't know much biology and programming?
The already has been a question about existing crowdsourcing projects in bioinformatics. The Multiple Sequence Alignment video game Phylo was one of the answers but it does not take advantage of the social aspect.
I'm not so much interested in existing implementations but rather I would like imagine some collaborations in the scale of 100s of millions of active users and 10s of social connections per user.
