1) It's now on our list to add signin without Facebook, since that's been such a popular request.
2) The problem there is that if you don't like your second match, then what? What's hard is that matchmaking isn't a common thing you pay for, so people aren't used to the risks involved. If you go to a restaurant, you generally don't ask to try out a meal for free, or ask for a second one if you don't like the first. If we were to provide two choices, we'd have to raise the price. We're the one matchmaking service where a personal matchmaker is going to send you a match for $20 .. most charge thousands.
Additionally, it's not so much about the business model as it is about trying to change the way people so quickly write one another off. If you know you only get one shot, and this person has been chosen specifically for you by a matchmaker, there's a much higher chance you'll give them a shot, which is what we want. People are far too picky and miss out on lots of great people. If you want 1,000 chances, there's always Tinder :)
And lastly, we're going to build a free match into the signup flow, so there's at least that :)
