I think the secret of Sally Traffic and Johnny Walker's chemistry and mutual sense of hilarity on a Friday was probably a bottle of wine next to the microphone. I like Sally, she seems like she'd be good value on a girl's night out.
I am fond of Ken Bruce - I love the way he sometimes makes little veiled comments that tell a bigger story. I'll never foget him having a real old dig at Sarah Kennedy without actually saying he was having a dig at her, ifywim. It was very cleverly done, full of subtle passive aggressiveness. I do cringe a bit at the obviously scripted comic lines that he and Lynne fluff between them though.
I am fond on JV even though sometimes he makes me shout at the radio in embarrassment because for a clever man he can ask some really stupid questions.
Chris Tarrant makes me want to stab the radio. Smug, self-important fake sounding twat who thinks it's all about him. He used to be great on Capital in the 80's - WTF happened? 
I am very fond of Steve Wright and Richard Madeley in spite of everything. I know, I know, it's wrong, but I can't help it. RM is Alan Partridge personified though.
I hated VF at first, which is saying something given the car crash that was Kennedy, but she is slowly worming her way into my affections. but even Sarah was like everyone's favourite batty aunt. She was beyond dreadful most of the time but every now and then she would show a flash of brillinace and she could be very funny.
LOVE LOVE LOVE Liza. She should have been given a bigger show, but I am sure in time she will have a prime time slot.
Zoe is delightful even if she does make my head spin a bit.
I hated Alex L at first but he is another one whose charms have crept up on me. Now I live in a different time zone he is my breakfast show, and I am very fond of him now.
Chris Evans - well he's a living legend. He's like a human jar of Marmite, but he has so much energy and enthusiasm and honesty that you have to love him a bit even if you hate him. I have followed CE since his days at GLR in the late 80's. I remember when he and Carol McGiffin (who was his producer at the time I think) came on air to say they'd got married completely out of the blue. I feel like he's a slightly wayward cousin I've seen the rise and fall and rise of! I love him, even if I sometimes wish he'd be less giddy. His wife must be a saint. She's got him right where he needs to be now though. 
Desmond Carrington and his fucking cat need to be drop-kicked into outer space.
