Have any of you found a Twitter app that can use the phone's GPS to find tweets from people in your geographic area? I used an app called Twitterific on the iPhone that had this feature and it was a great way to learn what's going on locally. The closest I've come is an app called Tweetkin. It works, but has some shortcomings. For example, it doesn't allow you to click on links. It also doesn't allow you to access your regular list of people you follow on Twitter. Thanks.
