Suppose user X comes in and ask "How is the group with professor Y at university Z ?". How should we treat this kind of questions ? One thing may be to answer with pure citation metrics, that is: they publish a lot, or they don't seem to. More personal experiences and opinions about Professor Y may trigger complaint from the professor him/herself.
I think questions about specific people or specific departments are not good questions for this site. It would be much better for the asker to directly contact students of the department/person in question.
