Services that have one tie or the other with geolocation keep flowing at a constant rate. One of the latest to crop up is Anttenna, and it actually bases its approach as much on Twitter as on location-based networks like Foursquare or Gowalla.
What Anttenna does is to let people publish microlistings that are sent to those who are located in their close geographical vicinity. The premise of the site is to make person-to- person exchanges and transactions come true in a way that does necessitate the users to travel all over the city just in order to meet. Also, the creation of a posting takes less than one minute, so busy people are catered in every sense.
Summing up, think of Anttenna as a sort of geo-tagged Twitter crossed with Craiglist and you are getting quite near the mark. These are quite strong (and useful) services to have as templates, and that makes this platform specially noteworthy. It takes what we already know and combines it in a way that maximizes the best of everything.
