How about meeting people with the same hobbies is great who are completely anonymous and only in 24 hours . That is great! After select some hobbies app will be match the other people who has same hobby. All you have to do is send a photo of whatever you want to introduce yourself to other peoples. No username , no person name totally anonymous.You wont be able to see your conversations after 24 hours. But you still have a chance to open a conversation with the same person :)
