Last week at GiveForward, we got the best follow up email from an interviewee perhaps in the history of EVER. Check it out it's pretty hilarious/awesome.
PS - we're also currently hiring a user interface designer. If you know some awesome send them to firstname.lastname@example.org. We're giving away $500 (or Chipotle burritos for a year) to anyone who refers us to the person we hire.
