So many of our tag wikis are small or non-existent that we really ought to do something about it.
In my data query here, I show that there are 168 tags that have no wiki and 26 that have no wiki excerpt, however, when I did a query for their names I got 131 tags; hence more than 130.
Either way, this is a big issue; how are users supposed to identify whether their question is on or off topic and then, what are we supposed to quote when users decide to post those questions anyway?
I have two ideas that I have posted as Community Wikis below. If you feel you can add anything to them or have a different idea, please edit or answer accordingly.
I'm particularly interested in any precedents you can find as these would show that this sort of thing is possible.
What do you think we should do?
