Nearby Tweets let’s you choose an exact (or not so exact) location, keyword and radius to search for anyone else that seems to be lsiting themselves in that area. The homepage is bright and clean with avatars of users nearby on the left and a stream on the right. A dropdown allows you to modify the search itself.
Hovering over the avatars shows the recent tweet and there is pretty much an endless stream on the right. You can narrow the range down to a couple miles or go as far out as 500. I can see this is a great way to check out what is going on for the evening in your local area or meet new friends. Tweetups seem hard to get hundreds to show for, mainly since they don’t follow you. Sending some @ messages of those in the nearby area is a sure way to get visibility and make new friends.
