Maybe the problem is we have too many admins? Having 8 admins online when there's 30 people in the server is overkill. When this happens, I suspect they become trigger-happy in wanting to be the first one to resolve an issue.
Not a question about JB specifically, but why are we promoting people when there are plenty of active admins online at all times of day? IMO, have a fixed set of admins that are active at certain times of day, if one starts becoming less active, demote him/her and promote a worthy candidate to fill.
