On a side note, I just joined Research Gate (my profile). I’ve noted that it generates kind of the same kind of belonging-to-a-group feeling that registering on Facebook did way back, when co-author after co-author starts following you. Still, I haven’t figured out exactly what to use it for yet; it certainly seem more useful than academia.edu, with abilities to ask questions etc., but is anyone of you really using ResearchGate for this? Or is it rather just another showcasing window for researchers (much like my Publications page)? Please feel free do add your opinions as comments to this post!
