Interesting idea for a "chat room" from Postlight:
- Create a Yap chat room.
- Invite others to join and talk.
- Share a URL of just about anything.
- Everyone gathering can comment on what you’ve shared.
- If you think your conversation deserves an audience, share the URL of your chat publicly.
- Only six people can join. Lots of people can observe if you invite them. But just six chatters.
