Hey, no need for the vitriol.

Dan, Wesley and I all did wheremyfriends.be -- Wesley was the submitter of the post you linked to, and mentioned both of us in the product description. We worked together on a bunch of apps and over the summer, and Dan returned to school and continued to work on Airtime while Wesley and I just graduated from the latest YC class.

As far as I know, Dan has never misrepresented his work and has extremely high integrity and character.
