What's Your Experience with Pioneer.app?

If you haven't heard of it before, Pioneer.app is an accelerator with a tournament-style selection system. Startups compete by submitting weekly updates, which are ranked by other startup founders. There's an ELO-like points system.

Wondering:

Do you know anyone who has been selected for the accelerator program?

How's the "product quality" of the accelerator program?

If you've been through ANY accelerator before, would you repeat the experience even if you could build and MVP and raise a seed round yourself?
