We carried the future, books and the trends tag out of the private beta. I believe we should eradicate them quickly before they grab hold, as they seem to be vehicles for list questions. Currently, I only see one question under books that hasn't been closed. Trends has only one occurrence, that one together with future, which in itself sounds like a pretty meaningless tag. Just try and come up with a wiki description for it and you'll know what I mean
Close votes needed:

If we can get them closed, that would solve our problems.
Detagging: Mathematical prerequisites for beginning graduate student in robotics (done), Robotics Trends (done)
