Gregg and Nathaniel (both of whom are notorious Gowalla cheats, which I would never do, no sir) chat a bit about Phat in the latest episode of Ruby5.
The Changelog crew also gave their take on Phat in a recent posting.
I’ve spent 100s of hours working on the technology behind Phat over the last six months. If you think it’s awesome, please consider recommending me on Working with Rails. I’m not asking for money, just an electronic thumbs up from my fellow Ruby community members. Thanks!
