I've got a smattering of upvotes on my small number of answers but my reputation has never budged. Can someone explain why this is so?

The questions that you have answered on MathOverflow are all "Community Wiki" posts, and votes on these don't affect reputation.

What are "Community Wiki" posts?

Questions that ask for a list of examples, and so don't have a single "correct" answer, are often made Community Wiki.

    I actually believe that the main goal/role of cw is to prevent people to get huge reputation based on big-list questions, and restrict getting reputation on somewhat mathematical contributions. – YCor Jul 14 at 9:51

    I guess that this has been discussed here many times, but it's probably worth mentioning that using CW as a way to avoid reputation gain (as mentioned in @YCor's comment) seems to be specific to MO and a few other sites. (It's not network-wide approach and possibility to make a post CW was intended for a different purpose.) – Martin Sleziak Jul 14 at 11:16
