The Kool Kids are all aTwitter about Bacn, which means non-spam email you don't want right now,
Bacn is email you receive that isn’t spam… And isn’t personal mail. It’s the middle class of email. It’s notifications of a new post to your Facebook wall or a new follower on Twitter. It’s the Google alert for your name and the newsletter from your favorite company.
Bah. Procmail is your friend. If you use 'nix email, anyway. My procmail rules are rather long and complex, but they do sort the Bacn and Sausage pretty well. It's the spam that bugs me, even with SpamAssassin working at full tilt.
