That is indeed a very bad blog. Kind of shows that whatever is the career path for becoming an MP, it probably doesn't involve the demonstration of brilliance at communication. One day we will isolate what the critical factor is, and neutralize it.

It occurred to me that having comments turned on is similar to the scientific peer-review process. Unless a journal is peer-reviewed, it's publications don't carry any weight in the field, and are generally only read outside scientific circles. For example, climate change denialists publish their theories in non-peer-reviewed newspapers, and do a lot of damage, because the public unfortunately doesn't know the difference.

Would it be possible to associate a further set of metrics for blogs that are just as accessible as the page rank? For example, number of comments, weighted by blogger identity, number of comments deleted/moderated, and so on.

I hate getting my comments deleted as much as the next person. If there was a firefox plug-in that cc-ed all my blogger comments to another server, and from which comments could be retrieved and reinserted seamlessly for anyone who had the plug-in, I'd use it. It would retrofix the feature back in, and easily highlight the policy for anyone to see, without the need for all that work you keep getting up to.
