# Future book trends: a decline in off-topic tags

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

Not Constructive: How can I start learning robotics?

If we can get them closed, that would solve our problems.

Detagging: Mathematical prerequisites for beginning graduate student in robotics (done), Robotics Trends (done)

Once they have been cleansed, can they not be blacklisted?

Questions such as "What book..." have no place on any SE site, and the books tag should be blocked.

{edit}

Sometimes, references to books is the ANSWER but should never be the QUESTION

• I'm not sure "What book ..." questions are off topic per se, as books already do come up in answers (e.g. Thrun's "Probabilistic Robotics" has been mentioned already). I can imagine a few sensible questions that would ask about a specific book, but I also think the research tag is adequate to cover those – ThomasH Nov 26 '12 at 23:12
• Tag blacklisting is generally for very serious cases when tags keep popping up. And question input blacklisting is also iffy (false positives/etc). Additionally, we may want to allow some types of Book questions, as long as they are specific to the topic and level (Physics does). – Manishearth Nov 27 '12 at 9:02
