Twitter can be a convenient way for you to keep up with your friends, and now it may allow you to keep up with Metro service disruptions.

Last month on inauguration weekend, Metro quietly launched Twitter feeds for each existing Metro line – Red, Blue, Green, Yellow and Orange. In the nearly four weeks since then, Metro’s Twitter feeds amassed about 330 users, only by word of mouth. We couldn’t find any official mention of it on Metro’s website.

Metro spokesperson Steven Taubenkibel said Metro is “looking for ways to reach our customer base” by providing riders with alternatives to get current information on the rail system’s status. People who would prefer not to fill their email or text messaging inboxes with status messages, for example, could monitor updates via Twitter.

The feeds are still in a testing phase, though, as Metro figures out how to best work within Twitter’s limitations, including its 140 character limit.
