There are some questions on this site that get a lot of views but don't have an answer. Some of them even have a high question score. Here are some examples (the two numbers behind the question are the score and the views as of Dec-22-2023):

I selected these using a query ("answers:0 and score:2 and closed:false and views:1000") or SEDE query, and picked the ones with the highest scores. Of course, that doesn't mean they are good questions, so check (and perhaps edit) before you place a bounty.
If you like one of them, though, you could put a bounty on it. If you don't want to spend your points, you can instead put a link of your favorite unanswered question in an answer to this post, and maybe someone else will sponsor a bounty (or answer it).
Of course, this is inspired by past bounty dances and similar events.
