Show HN: Turn any WiFi into a persistent group chat

Try it out on your WiFi: https://tapchat.com I’ve always been shocked at the fact that it’s easier to chat with someone on the other side of the world than with someone who is on the exact same WiFi as you. Think about how many other people have used or will use the same WiFi as you at home, school, work, or in public; and so far it has been practically impossible to chat or share pictures with them. So far a great use case I’ve seen are college campuses where thousands of students connect to the same WiFi, and who can now all chat with each other.
