Best i can tell, there is a new generation of "journalists" coming onboard that have been trained in the style of "blogs".

And it seems to be far from unique to the BBC, you can notice it with all the national broadcasters (Though BBC being English and thus have a worldwide reach in its original form, is more noticeable outside of the UK).

Blair made them compete on ratings which is retarded when you have a guaranteed income. Another thing he ruined.
