Yeah, I'm totally lost too, after reading the about and how it works pages. Just not sure what problem I have that it's trying to solve, that something else doesn't already solve anyway... Care to clarify on here?

you have historical + real-time statistics to base your submission decisions on before spending any money.

the sites that drive lots of traffic do so in opaque ways. as a result, people try to manipulate them (e.g. google, digg).

this is a completely transparent solution, in theory at least. let me know if this makes sense - no doubt an ongoing process of perfecting the pitch.
