MS debuts Vine, an app for real-time community coordinating

I'm gonna say "no". First of all, because it's a widget at heart. I see it allows some sort of mobile alerts, but a game-changing app will probably be much more mobile-centric.

Second, because it looks like MS is gonna try to route adoption of this tool through local governments. As Craigslist and Facebook have proven, regionally-based apps/networks grow better when they're not managed by the governing institution.

The idea of alerting people of local emergencies is a nice one, but Twitter has already given us a glimpse of its usefulness in that regard.
