"I couldn't find a better SE site for this question" is not necessarily a reason to ask it here
The help centerhelp center describes what kinds of questions are considered on-topic here, as well as some kinds of questions that are outside the scope of this site (as defined by the community).
We welcome your on-topic contributions. But, if you ask a question that is not within one of the on-topic areas, or that falls within one of the out-of-scope areas, it will be closed.
This is true even if there is currently no StackExchange site (or other site) at which you may ask the question. Off-topic-ness everywhere else does not imply on-topic-ness here.
Furthermore, while some users may suggest a better site1 to ask your question if they know of one, we aren't necessarily experts on all the websites out there. So if you ask in a comment
well, what site can I ask this question at, then????
you may or may not get a response - because we don't necessarily know the answer. But it definitely won't get the question reopened.
If you think you've identified a gap in the coverage of current StackExchange sites, you can visit Area51 to propose a new site, or support an existing proposal.
1 Cross-posting is against StackExchange policy and is liable to get your question closed and deleted. If you think your own question would be more appropriate on a different site, use the "flag" link and ask a moderator to migrate it from Academia to your preferred site. If you think someone else's question would be more appropriate on another site, write a comment suggesting that the OP use the "flag" link to ask a moderator to migrate it (and, also vote to close if it's also off-topic at Academia).
