So, is anybody here <i>actually</i> active on academia.edu? Asking, since as a computer vision researcher (3D reconstruction, obstacle recognition/identification, augmented reality, ...) I am constantly looking for scientific resources, and to be frank, it is quite annoying because it can become really time consuming.<p>So a genuine question, is the site worth signing up for? I remember when mendeley just started, there was lots of excitement about it, mainly because it was sort of marketed as <i>the last.fm of research</i> (giving you <i>good</i> recommendations for <i>your</i> scientific interests), but then it turned out to be just <i>meeh</i> (getting bought by Elsevier didn't help much ;-).<p>Also, on a side note, are there any other good sites doing something similar out there (like a reddit/HN for <i>insert your research interests here</i> type of site) that are actually any good? I'm sure there must be a lot of other researchers active on HN...
