my gmail filters started blowing up some time ago -- a year or two? i variously deactivated some/all/etc., re-activated, re-created, broke-out, aggregated, etc. none of it really seems to matter. i don't actually get a lot of mail, i just stopped checking all day every day, so i started missing a lot of stuff b/c i would just never catch up.
