This doesn't solve the problem of making the first move, since you can't know that the person adding you to the crush list is actually doing so because they have a crush on you. They may just do it to see if you have a crush on them.
It's a good problem to solve, but I think that after a short burst of initial activity everyone will realise how exploitable this is and so be unable to use it seriously.
I imagine most people after the age of 18 stop doing that, so I guess this might solve a problem provided there are some age limitations. Then again, you have to wonder if people older than 18 have 'crushes' they can't resolve like adults.
You Americans make it too complicated :)
So we created PairBuddy. Please give us your constructive feedback.
Thanks!
Concering growth/spreading of the project: BangWithFriends had huge media coverage because it was something new and also a little controversial. I'm afraid PairBuddy is missing this aspect.
I nonetheless with you the very best of luck with your weekend project.
