Cool product! I have two bits of UX feedback:

1) in step 2, after you click on Yes/No/Don't Know, there isn't enough feedback in the product that indicates that you successfully answered the question. I originally thought that the web request failed to send and didn't notice that the two questions presented were different.

2) When does a person ever reach step 3? It doesn't appear to be the case for me, you can circumvent reaching step 3 thru the possible matches. I think this is misleading and confusing.
