Are questions about the usage of spreadsheets in general ok for this site?

I see many questions like this that seem to be questions of how to do something in ANY spreadsheet in general. Are these questions inside the scope of this site?

If not, should (or can) we mark these questions as irrelevant (or out of scope) so that we can remove these from searching?

Personally I believe those questions to be fine here, as well as those which are specific to LibreOffice. In this line, I suppose that only questions specific to other suites are off-topic here. We help LibreOffice users, and they may have both general and specific questions, and they might not (and don’t have to) know if a specific question generic or specific.
