Currently there are "only" 100 users with >3000 reputation, i.e. who can vote to migrate a question. Everyone else (over 15 anyway) can only flag what seem to be "obvious" migration questions (possibly a contentious example, but let's say Home Networking, which consensus indicates is SU material).
So: is it appropriate to be flagging these sort of questions, instead of waiting for someone with enough rep to come along and do it for us?
My apologies if this is a dumb question, but "flag for moderator attention" feels like one of those things that deserves a little bit of caution before using; after all, I don't want a hundred serial downvotes from moderators who are sick of false flaggings ;)
