definetly the best twitter app! I would recommend you setup a website just for this app!
i was using tiny twitter before, it has this cool feature:
Geolocation: if you have a GPS you can tell everyone where you are. It takes the boring latitude and longitude numbers your GPS returns (built in or bluetooth connected) and can do a reverse address lookup to tell you where you are near (not close enough for stalkers to find you!) and posts it to your timeline along with a
Live Maps link so people can see where you are on a map as well.
maybe you could implement something like this in the future
great app!
