(summarizing some observations from the chat).<p>I really like the idea. I can see myself using it at coffee shops, or other places for impromptu groups.<p>I wouldn't mind seeing a web-app just because I think that would be even easier to pull people in with. Installing something just for a quick chat might be too much for people, or might not even be possible, i.e. wanting a quick group chat but you're at a public library computer.<p>All in all though, it's a cool idea, and solid little app. Also ethpressO was very nice and engaging in the chat :-)
