I occasionally get a bit enthusiastic and jog on over to one of the SE Betas to propose changes to minor things that don't quite smell right (generally re-tagging, or tag-synonymizing (the proposal restrictions to which, I detest), for example).
Generally, I try to ask the Beta Meta whether a change should be made, but I have jumped the gun on occasion (and have no problem reverting if requested to). Other times, I wait, but for how long? And how much positive feedback should I wait for before enacting a change? I'd say we have about 3-4 really "active" people doing the work there, but since it's a slow-paced SE community, "active" doesn't necessarily mean "present", and let's get real : I don't expect unpaid moderators to check in or answer every meta question.
Good feedback (4 upvotes, comments by 3+ people) sometimes takes a few weeks. Sometimes I might have already taken action due to my own impatience and excitement.
In general, how long should one be patient for?
