Within the general domain of post-pub commenting we now have open choices between Research Gate, Publons, PubPeer (both of which cold-pinged me), Kudos and PubMed commons. I have joined in with the latter and I note Kudos has just gained the implicit recommendation of ORCID.
Given that life is not long, which of these would folks recommend on the basis of detailed engagement (even for just one of course)?
P.S. if representatives from any of these see fit to make comparative factual comments that's fine but please declare your interests.
I moved this to forum since it's probably a better fit there (if anyone disagrees they should feel free to move it back to the questions section).
BTW, I also changed the title. I assume you meant "Portal of choice" or "Site of choice" rather than "Paralysis of choice", since I think we'd all prefer "no paralysis".
