The post below is just a joke linked to via my comments on Captain Oblivious aka Rob McDonagh's post concerning blogging and how one could face their blogging past again someday when running for a political office.
As many blogs are started, left to die, abandoned, etc. I think one of the most difficult tasks, especially if it would be years down the road, would be proving the authenticity of a post and attributing it to a specific individual.
And will you believe the politician that says, "I tried it once. I made one post, but I did not publish it."
