I agree that Grouper's approach of six people is much better. To the founders of this project, I recommend you move the bit explaining the price to the top. It's this piece:

> We charge $75 up front because people who are serious about going out are willing to pay this (so it acts as a filter for our matchmakers).

It's a very good explanation and it needs to be said upfront because otherwise people who have seen Grouper will be outraged.
