I have long, long since unsubscribed from all e-mails from academia.edu, and I’ve very largely ignored it for years. I‘ve certainly never dabbled with the “pro” version. I did upload copies of IFL and IGT when I had recovered the copyright, and later replaced the old TYL Guide. But otherwise I’ve kept my presence there pretty minimal and not used the site at all.
However, I was alerted recently to the fact that a (very) old version of my notes of category theory were still being downloaded from there. So I thought I should either replace those notes or perhaps just remove myself from academia.edu (as I had got the impression that it really isn’t in favour).
I was a bit staggered to find, then, that despite the non-activity on my part and despite still having only eight live pieces there, the site reports 175K “views” over the years. I’m pretty sceptical. But I did find hundreds of recent messages from downloaders that I’d not acknowledged (apologies, then, to those who thought I was just being rude!).
So I’ve decided to keep my profile there for the moment. But is academia.edu really much used these days? What do people use instead, if anything?
