You can read my whole spiel at http://www.circleofconversation.com/#tab=theory, but basically the idea behind the app is that people like talking to strangers online(like we're doing right now) as long as there is a sufficiently precise topical specifier(like we have here). The app attempts to accomplish this by letting users give their chat rooms tags which fade out over time and then disappear if they aren't refreshed/spoken aloud. They're constantly replaced by now-accurate tags, so ideally every conversation has a very precise set of topical specifiers at all times, making them worth joining.
I'd love to get some feedback on the general concept as well as execution specifics, though the UI is rough and the feature set is basic. Thanks, HN.
P.S. I'm intentionally posting this in the evening to try to avoid any significant traffic, and to give myself time to hot-fox any glaring bugs, since I do client work during the day. I bet this sounds familiar to at least half of HN's readers.
