Labour deputy leadership hopeful Jon Cruddas hasn't really entered into the cut and thrust of this newfangled blogging malarkey. In the two days since his campaign blog has been available online, we have yet to see a second post or indeed a second comment.

New Labour blogger Jo Salmon - who appears to be one of those clever people who actually know about 'pooters and stuff - has come up with a plausible explanation for this:

'It’s quite likely that this is actually - wait for it… - a preview of his site and we shouldn’t be seeing it yet.'

It all gets highly techie after that, concluding with the recommendation to 'use the ‘clean post slugs’ rather than the p=3 slugs…'. Whatever that means.
