It should be possible to implement additional "advanced search" features to support such functionality. Right now you can search on questions by views, votes, and how many answers they have, but you can't search by the max votes on answers (as requested). I don't see any reason why (in principle) a
max-answer-vote search key couldn't be added.
Then you could search for (e.g):
views:1000 max-answer-vote:4 => Questions with at least 1000 views having no answers voted higher than 4
votes:10 max-answer-vote:4 => Questions voted 10 or higher having no answers voted higher than 4
You could decide for yourself what combination of votes and views makes a question "popular."
