A new take on commenting papers.

citeulike+disqus mashup. Find abstracts and comment on them.

I can’t see it going very far right now, but it’s a good start. It’s scanning the citeulike database to get the abstracts and is using the Disqus commenting engine. I am not sure how a decentralized system like this could be convenient for the users. The main problem I see with it is having the comments separated from the paper. They also need to reach a critical mass of users to make it worthwhile. What I would like to see is using Disqus (or something equivalent) directly with the publishers, or with the major databases (Scopus, Mendeley, etc…).
