You're right moot, blogs are fascinating in the local context, for their impact on the traditional media.
And it is good to see politicians embrace them. Those that I have seen interviewed by VFC (Shenton, Crowcroft, Le Herrissier, Cohen, Syvret, even Terry Le Sueur) generally come out of it looking better than had they not participated.
I imagine there is a big "fear of the unknown" for some old school politicians, but they should just embrace it. Sarah is right to highlight issues of editorial control though - nobody wants to be edited unfairly, with no right of appeal. I guess over time some trust will build up between local bloggers and the politicos - it seems to be going that way.
What a video blog needs is a good personality. VFC is great because he has a unique style in local journalism, he's different to the paid journalists. If I were the traditional local media, I'd get a "star blogger" on their sites, one with a personality, who could build up a following. CTV could do a lot worse than Jess Dunsdon after her Paxman-esque exploits this week.
