Well, just got off the phone with someone who is working on an open, centralized, system to comment on/rate all journal articles. If all scientists used such a system that could be quite useful though I told the person, as I have said many times before, I am skeptical that people will use such a system when they can (and do) comment on papers in their social networks. Anyway, this person asked if I could come up with a list of people who might be interested in being Beta testers of such a system. So I am asking here - any volunteers? Any recommended people who you know do a lot of commenting already in other places?
