Where's the right place to ask meta questions about stack exchange in general, not just about a specific stack exchange site?
For example, I tried to find out how to put links into comments and found the answer on programmers.stackexchange.com. (I'm sure I could have found the answer also on meta stackoverflow, but that's beside the point.)
Where would I ask such a question? Is there a general meta stackexchange site? Take this question for example, it is not connected to stackoverflow, I could have asked it also on meta.beer.stackexchange.com.
Interestingly, meta.stackexchange.com redirects to meta.stackoverflow.com. Can I consider this meta site as the most general one?
