It's been about a year since I've touched it, so it's probably a little rusty, but I made a website with a similar premise.
I love the here and there buttons.
Giving this a go. Had a few issues on signup, Chrome on Mac wasn't allowing me to pass the point of picking 5 interests. Firefox allowed me to go further, but now I keep getting the 'Space Incomplete' message at the top. Not sure if all that work was wasted, I hope not. Looks fun though.
There was a problem with search which I just fixed. I'm not sure if that was the cause of your problem, but it was the cause of a bunch of other problems. Let me know if it's any better for you.
