Sidekiq is special because it's crazy performant, and it _works_.

Mike has built a system that's rock solid, and he doesn't twiddle around with it willy nilly. He keeps it super stable.

The people paying for it (I'm one of those people) are paying for the reliability, in addition to the features.

Mike's also managed to find a real sweet-spot with the features he holds out for Pro/Enterprise. The stratification is just right to nudge you up, but it always feels like you're getting a good deal when you pay.
