SAN FRANCISCO - Twitter, the social-networking service that delivers 140-character messages, will soon let users share their location when they post Tweets.
The feature, which relies on the global positioning system, will require users’ permission to show locations, said Biz Stone, cofounder of Twitter Inc. “It records location along with every Tweet,’’ he said. “It allows for some really interesting context.’’
Twitter currently lets users put their locations in their accounts, though the information may be inaccurate or unspecific, Stone said.
Twitter will make the new feature available to outside software developers, who will build it into their programs, Stone said. The service will give exact locations. It will be available in the next two or three weeks.
An application might be able to show what people are Tweeting about in a two-mile radius, Stone said. While some developers are already providing similar features, those services haven’t been supported by Twitter.
“Developers have been doing cool stuff, but they haven’t had the proper support,’’ he said.
