To all sarcastic commenters:

Hey, dudes: he built a bunch of cool and famous software, some of which you are using without paying a dime for, and even making money with.

He has no blog. Can't be found on Facebook. Apparently doesn't even like surfing web. But there is a wiki page about him and he gets recognized while walking down the street.

His name is Richard Stallman. What is YOUR name? What have YOU built?
