I just found the future tag on Stack Overflow.
Most questions there (now 109 non-closed) ask about events that will or will not happen in the future (relative to the time the question was asked or is read).
Most of these are either off-topic (not about programming), not constructive ("What do you think will happen?") or not a real question.
There are some legitimate questions here, about the future construct in concurrent programming, or about the from __future__ import ... feature in Python (though maybe those should get different tags).
So, if you can vote to close, help us looking at those questions and close the ones which are not suitable for Stack Overflow. Please do not vote to migrate to Programmers Stack Exchange, as they don't want prophesy questions, either.
Some of these questions might also be saved by a good edit. Though have a look at existing answers first.
It might also help to write a good tag wiki to avoid new questions about the future.
