A method of electronic communication, primarily used to inform you that your penis is too small.
Also came across this collection of manifestos and other writings on entrepreneurship on the web at ChangeThis. This is what they say about themselves.
ChangeThis is creating a new kind of media. A form of media that uses existing tools (like PDFs, blogs and the web) to challenge the way ideas are created and spread.
Stuff by people like Hugh MacLeod, of Gaping Void fame, marketing guru Seth Godin, and Guy Kawasaki, a former Apple evangelist and entrepreneur par excellence. Damn nice stuff to read up there. I suggest you sure pay a visit.
