I don't mind him at all, very relaxed and natural, seems to get the best out of guests who are clearly at ease with him.
He's genuinely quick-witted and comes out with some pretty funny comments. He's like a male version of Sara Cox - maybe a bit marmite, but you can't please everyone.
To compare him to Moyles' show is unfair - he presents pretty much single-handedly whereas Moyles had his Steve-Wright-style "posse" of Comedy Dave, Aled, Dom, Tina etc.
I'm 38, so certainly not "demographic" but I listen to R1 from dawn to dusk and I still think it's the benchmark that all radio should be judged against.
The mistake the Beeb are making is trying to change R1 to attract the yoof rather than letting a successful product mature with it's listeners and offering a new product for young listeners. They have no understanding of how brands work.
