Here's an idea for using Twitter geo: a service to direct message me the weather (current and forecast) based on where I am via Twitter geo. Let's also get some news in there as well. Can also be tied into Foursquare geo. Basically, push me information I'll want on a regular basis, like a 7:00am local time DM that tells me what I should wear that day -- tank top or parka? And I don't ever have to figure out where I am, it just knows, and I don't have to check one more thing. Just log into my Twitter account and there it is.
