Zero inbox merit badge
Here's a "nerd merit badge" for having an empty inbox. (One of a line of a whole line of badges.) For the record, I recommend earning this badge once a day, every day.
To learn how to zero your inbox, read the brief description in Uncle Mark 2009 or the longer take in Bit Literacy.
(Thanks to Gary Peare for the shoutout in the BoingBoing comments, too.)
I love this... we need another one for "Mind like water" or "Dumb and Happy" :)
