This question already has an answer here:
As a moderator on HSM, I'm notified when a new meta post is started on HSM meta by a diamond on the top bar lighting up in blue. Here it is, not lit up.
Don't judge the big bright orange 12; we're going through a site self-evaluation as of this screenshot.
On other sites, I'm extremely active on meta, occasionally more so than on the main site itself. I check daily for new and/or active questions.
Proposal: Let users of sufficiently high rep see the same notifications as moderators. This would be quite handy for those active on meta.
One thing to consider, though, is that not all high-rep users are active on meta, and not all users active on meta have a lot of rep. I would guess there is a correlation, but I can't support that hypothesis.
I considered posting this on What privilege should 30k users get?, but I don't think it should be limited to those with 30k rep.
