I've been working towards launching a startup called Bibdex (http://www.bibdex.com) for a little while now. I want to help all research-oriented fields to sift through the large number of publications.
It's amazing how many articles and manuscripts are published every day, not to mention blog posts and social commentary. Unlike the average person's surfing habits online, professionals in these fields are required to be on top of the available research, but most of the available research is not very good. That seems like a problem worth solving, and a potentially profitable one if industrial and institutional researchers are willing to pay to save their time and publish higher quality research.
I'm curious. Have you seen http://www.mendeley.com yet? If you have, why doesn't that solve the problem for you?

P.S. I'm interested in having other people join as co-founders.
