For what it's worth Carl, I really appreciate councillors being accessible on Twitter, and think it's quite important that they do engage rather than just posting short-form 'press releases'. My own local councillors make a fair effort on the engagement front, both individually and via a team account. The latter is my main source of information about what they do as well as an occasional channel for contact - without the human touch of replies and engagement, I probably wouldn't stick around just for the announcements.
