Several takes on the #DeleteAcademiaEdu thing. First off, let’s not forget that academia.edu is a (for profit) social network, not a repository. In the academic rat’s race, every mean to get one’s work out there is justified, so deleting profiles might be a luxury only established folks can afford. Also, not all researchers have access to an institutional repository. Personally, I kept my (few) publications on my former institution’s IR and only linked them from my academia.edu profile. This is the approach I recommend when asked.
