Tweeting up Pittsburgh Transit Authority

I've had a lot to Tweet about lately regarding the service that Pittsburgh Area Transit (PAT) offers.  Mostly bad, and a little good. 
 
However, I've been thrilled at the uptick in Tweets from @PghTransit listing the outages and schedule changes during the inclement weather.  Granted PAT has much to improve on still - I almost missed a bus last night because the sign wasn't lit and snow wasn't cleared at the stop - but the Twittering at least indicates an attempt to communicate better and a commitment to improved customer relations.  This article ( http://bit.ly/bOy7c8) at Pittsburgh City Paper discusses the Twitter iniative at PAT.
 
One thing the article mentions is that the Twittering, from customers, is a great way to inject some crowdsourcing to help distribute route / scheduling information.  And PAT mentions that they've applied for a grant to do realtime updates.    I'd love to see realtime updates coming on my Twitter account.   I could imagine being able to "Follow" my route and get updated information on my phone while I'm waiting.   There are already some systems that can do this.  But a low-tech way, that wouldn't require a grant would be to setup Twitter accounts for each bus line (ie., PghTransit-68A) and then riders could Tweet from stops (like @PghTransit-HP Smithfield & Liberty 5 mins late).
 
How about it?  Time to start tweeting if you're riding the bus.
