Show HN: Weekend project, "I love you, but"

I built a little app that lets people anonymously send messages to other people -- though, I purposely tried to target it towards people that might really like this sort of stuff. :) Truthfully, I think I overheard some high schoolers saying "I love you, but..." a million times at a coffee shop yesterday but I digress. Would you guys mind harassing your friends in the interest of helping me iron out some kinks? http://www.ilubut.com
