    Comments on Science▲10

    Comments on Science is a free and public user-generated database of scientific comments. Commenting on papers in academic journals is a complicated process, with many steps between an idea for a comment and the appearance of that comment in a (mostly closed-access) publication. The goal of Comments on Science is to reduce this friction and enable accessible and free scientific communication. About the site: I decided to build something useful in the month of May and this is what I made.

It's all over the place. Seperately, we know that the link aggregation style has a good reputation. It's a good stimulation for discussion. What do you think of it?
