Sinn Fein and new media

As one fairly new to the world of Twitter, I owe Mick and a number of others thanks for pointing me in the direction of this fascinating and seemingly effective use of new media by Sinn Fein in Mary Street, Dublin. As Mick put it, Sinn Fein appear to be streets ahead of the Irish pack with their engagement of new media. A sign of things to come in Belfast, Derry and elsewhere?
