The Spanish Town That Runs on Twitter

I can't help but admire the pragmatism of the mayor, but do have niggling concerns at the back of my mind about providing public services through a proprietary channel that they have no control over. For example. what happens if Twitter goes bust? Or Twitter decide to blacklist the mayor's account for some reason.

I suppose any negatives are mitigated by a) the likelihood of Twitter going bust or playing foul is remote, b) the town can always transition to another network if needed, c) most people have Twitter installed on their mobiles already, removing the hassle of having to download and learn another app.
