YakShaving: I totally "invented" airtime 2 years ago

I'm not sure if I really get that the idea is really worth $33M in funding. I saw it more of a cool side project that I'd use.
In fact, I don't particularly like Airtime's execution. I'd have done it pretty differently. If they're curious to know how, they can ask me :)
The idea is not worth $33m. The execution, over time, is what might be. The thousands of ideas that were considered, discarded and the hundreds that made it into the current offering are worth close to $0.
