In the first post of his new blog, he outlines his reasons for switching sites:
"The drawback with the 6 Music diary was that a) the BBC had to stress at the end of each entry that my views were not necessarily those of the corporation's - which of course they're not - and b) I had no access to it. I just delivered the words once a week and they were added to the site by someone with the accreditation and software to get under the bonnet. I became a passive observer of my own blog, unable without a palaver to go back in and tweak things. Or indeed to add a two-line ponder on a Tuesday evening about Larry David or coal tits."
Shame on the BBC for not giving him access to blog-writing tools proper. Although well done for giving Nick Robinson a proper blog (powered by Movable Type), especially after Paul Mason argued that it was better to be using the software that everyone else is, rather than developing your own in-house stuff.
