I like the idea of a public space for discussing and commenting on journal articles. Anyone here on ResearchGate using it? What's your experience been?
On the tests that I have done, the PubPeer database seems very empty, even when I know a DOI is likely to be involved. I can find more researchers in an area by using the same keywords in ResearchGate. The only thing that RG does not provide is anonymity, which is probably a good decision by ResearchGate.
