Wow, this is an incredible reply. Thanks so much for such an in-depth analysis and compliments!

I actually really like your mock-up and really appreciate that you took the time to make it. Hopefully you don't mind if I take quite a bit of inspiration from it, because I definitely think it looks much better than my current one.

Yeah, I agree that the network effect is one of the biggest problems. Retention seems very tricky with a concept like this because while posting it to reddit or HN can result in many registrations, few people stick around because there isn't much to do on the site because there's so few users at the moment. It honestly does make motivation pretty difficult, but I am indeed going to stick with it regardless.

With regard to your last 4 numbered points, currently 0% == not answered == neutral, and this is mostly due to technical limitations. Your default similarity cube is just (0.0, 0.0, 0.0, 0.0, 0.0, ..., 0.0) (50 zeroes), and voting on cards adjusts this accordingly. Such that if you answer 100% to every card in the first cluster and answer no other cards then your CUBE would look like (1.0, 0.0, 0.0, 0.0, 0.0, ..., 0.0)

I was thinking about a potential way to solve this, but as of right now due to the constraints of CUBE similarity matching, this is the current solution.

Thanks again for such an insightful reply!

Feel free to use it however you want :)

Regarding the 0.0/default/skipped -- see my other response about "cardsets", which the more I think about it, the more I am convinced will solve nearly all of your issues:

  - you don't have to worry about the skipped vs neutral problem (as it is fair to expect a user to answer all cards in a cardset).
  - you don't have to worry about clustering. a cardset is a "cluster".
  - you can work around technical limitations by having each cardset be its own cube
  - you boost retention by being able to have a library of dozens of cardsets (rather than 250 cards).  limitless swiping, and swiping on things that your users will find interesting because they are selecting cardsets that are important to them.
  - you can make your site viral by allowing users to send a link where the receiver can (anonymously) swipe all the cards of a cardset and see their "similarity" to the link sender.  (Then you can ask them to register to be able to send links themselves).
  - futures paths for revenue are endless

I think you are 100% right here. Wow, thanks so much. This really is amazing. I'm going to begin work on this soon (just need to get some sleep first!)
