See what others around you are tweeting with Nearby
If you interact with a lot of close friends on Twitter, you might start noticing some friends are closer to you than you think. The social network is, via TechCrunch, testing out a brand new service called Nearby, which would roll out tweets by users in the same area, whether you follow them or not.
It's experimental thus far because, as you can imagine, many users either don't want to use their location attached to their tweets or they don't want to be bothered with who's tweeting what just because they happen to be in a geographically similar location. Only some users have access to the tool at present, though it's interesting to note that it has been available to Twitter users surfing on third-party apps for some time now. Twitter's implementation will almost certainly add another dimension of personalization, but it's nothing definite as of yet.
Would Nearby benefit you in ways that you'd want to sacrifice "true" location-based privacy for?
