Also, look who didn't actually write wheremyfriends.be but is taking the credit for it? http://news.ycombinator.com/item?id=2245016
Yes, Mr. Dan 'I didn't actually ship it' Shipper.
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.
Anyone who has actually dealt with Dan in person knows that he is a humble, quiet guy who would never seek to misrepresent his work in any way.
I first met Dan shortly after the launch of wheremyfriends.be, and he was effusive in his praise of the work both Wesley and Ajay had done as they collaborated on the project.
