Greater ministerial accountability or mere profiling?

Thanks to Mary Reid I've learnt that David Miliband has become the first minister to start a blog.

Sadly Not So Very New Labour have made media management such a fine art form that one invariably asks whether Miliband has genuinely done this in the hope that it will

help bridge the gap - the growing and potentially dangerous gap - between politicians and the public

or is just a means to boost his profile at large for the forthcoming contest to succeed Tony Blair against Old Man Brown. I hope it's the former, in which case this is an encouraging development.
