This from Ken at Militant Moderate is a nice analysis of the way blogging could be used by politicians and their supporters in the future. I think, overall, I agree with him; blogging is at its best when talking through policy and ideas rather than personality and gossip (although, let's face it, the latter can be fun(ny) at times). Huhne was very popular amongst the LibDem bloggers precisely because he engaged the policy debate strongly, and has done his future prospects a world of good by running I think.
Also, this on the Snow in Summer. The GOD corporation has a record of its discussions with Tony, but they're protected by client priviledge. Definately worth a read through.
