I remember you doing exactly that with Hacker Newsletter. :)
That is great advice though - I had several Google and Twitter alerts setup, but then I realized I was never doing anything with them so I axed 'em. Another thing to watch out for is recurring todo list items that you never actually do.
Non-profits that send monthly updates that merely highlight a member are particularly infuriating to me. Tell me of a new project when it launches or a big milestone reached. Letters sent for the sake of "just checking in" make me ignore subsequent emails. I get newsletter blindness almost as fast as ad blindness.
