This is pretty good for work e-mail, but I 100% disagree on not using filters in personal stuff. I get a lot of notifications - forum replies, twitter follows, upcoming concerts, facebook stuff - that I absolutely don't need to see in my inbox.

Thanks. I probably should have added: for that kind of stuff, I aggressively unsubscribe. Consider that tip #11 :)

I want some of that stuff. I don't visit Facebook on its own, so I need the reminders. I don't crawl concert sites on my own, so I like being notified of that stuff. But none of that ever requires my immediate attention.
