(0) How to find out for an MO question at hand whether it already has anything like its canonical meta-thread?
(1) Should, in your opinion, every MO question automatically generate a meta-thread of its own, reachable by a "meta"-button on its non-meta parent (and vice-versa, the parent reachable via a "parent" button on the meta-thread)? Has this meta-meta question been discussed on meta already?
EDIT: no, there should not be any automatism.
This is very likely to have been asked on MO.meta before, but I did not find it, despite a (cursory) search.
One of my motivations for asking this is that on several occasion I have encoutered comments on MO about which I think something along the lines of " one should get someone to correct this comment."
Then, one finds oneself at a loss what to routinely do: comment oneself (hoping for the pinging to work), flag (which most of the time seems excessive-one should flag sparingly), or turn to meta. But where on MO.meta to turn to for a particular question at hand?
- Of course, my question (0) rests on an implicit premise, which is questionable, namely that there is any such thing as the canonical meta-thread to a question if it has one.
