If I were single I would be using this. I'm totally blind so Tinder has never been useful to me. I don't know how well it would work but I could see having my friends help me train it by describing pictures to me. I was never a big fan of the like absolutely everyone option, I felt like it would be hard to start a conversation. "Why did you like me?" "The algorithm I use to make up for the fact that I can't see your picture decided I should like you." would at least be a unique way to start a conversation.
