Interesting concept, and congratulations on shipping! I think you should rework the copy ("you group = liked"?!), but I'm interested in seeing whether this gets traction.
I'm based in Japan, where people usually like to meet in groups, even for romantic relationships (look for gōkon[1]), so if you don't have the growth you're looking for in the US, try on the other side of the Pacific. Ping me if you have a question.
