Mods are 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:
Proposal: Let users of sufficiently high rep see the same notifications as moderators. This would be quite handy for those active on meta.
(1) How does the diamond know when to turn back off?
(2) I assume this is only active on given main sites, like site-X, and only indicates for meta-X? That is, it is not universal, meaning, you do not see meta-X alerts while on, say, Stack Apps.
(3) Would this not get annoying if every SE site did this?
After you visit the meta site.
Yes. You also wouldn't see Meta.SE alerts anywhere (maybe SE homepage?). Only the
meta.site.se
would be shows onsite.se
Only lighting up - not a big thing.
Can a userscript / extension be created that would do this? I'm not sure if there is an API / reliable method for detecting posts.
