One thing i especially love him for is the creation of McSweeney's, and the amazing website McSweeney's Internet Tendency, because it is clever, funny, and full of stuff to distract me from revising for my drama A level. Through 826 and McSweeney's i've discovered lots of truly amazing writers, so i thank Dave Eggers for that too.
If you haven't read McSweeney's before, this is my gift to you.
