It's even worse than that. The big difference between the two was press coverage. The GP actually has it backwards. flavors.me was out well before about.me started, but when about.me launched they generated a massive amount of buzz, in particular on TC. It effectively left flavors.ms in the dust even though flavors was always the better product. Better IMO, of course.

edit: GP didn't get it wrong, I just read it backwards. Still, sad to see hype trump quality.
