Location-based services are likely to be the next big thing in telecom. Twitter is getting its ducks in a row according to NYT. There are a bunch of possible uses for location-aware tweets. With this new feature, Twitter users — many of whom use the service from their phones while on the move — could choose to view all the tweets written by people in their city, neighborhood or building, for example. In a post on the company blog, Biz Stone, a Twitter founder, suggested that the feature would be particularly useful for people following an event like a concert or an earthquake.
