I recently put together Umhai.com with the same software that Wordpress.com uses - wpmu. The tagline is “Let’s put threads everywhere” with the hope that you could create live threads for any place you could possibly want them. Places like cafes, libraries, dorms, office buildings and any other places people are often connected on their computers but cannot really communicate. I would hope the service might accomplish something interesting that twitter, brightkite and foursquare don’t quite. Twitter provides an awesome ecosystem but it is sometimes difficult to find “threads” or conversations. Same for brightkite. And foursquare doesn’t really allow for conversation, it is primarily a game.
Right now I have a few cities set up where you can add threads for any places you like. I have started adding quite threads for the SF Bay Area, most of them being places in Berkeley.
The site needs to progress with some more custom coded features but these things are beyond me. So far I have primarily just used free plugins for wordpress. More advanced navigation, search and others will really be helpful. So I’m looking for help. If you know anyone that has coding skills and would like to be a part of a project like this please send them my way. I would love to have fun with it and see if we could make a useful tool for a lot of people in the Bay starting with the Berkeley area.
