It's interesting that you enjoy SK because I find him similar to commercial DJs. Lovely, lovely guy who plays great music sometimes but I don't enjoy the show's vibe (which has probably been dictated to him).
I still think it would be best for 6 Music to go. I don't see why a commercial interest couldn't negotiate the rights to access all of the BBC archives. Anyone who takes it over would surely want to retain the bits that work, otherwise, they'll waste their money.
There is a huge difference between the quality of drama produced in this country and in the US, which is largely down to funding issues. Probably why it makes Chutes' teeth grind. It is not great. Yet, most people would prefer better TV output (I agree btw we should put BBC3 out of its' misery). If the figures are broadly correct, TV viewing massively outweighs 6 Music listeners. Those veiwers could legitimately question why money, that could be used to find the next Gavin and Stacey, The Office, Dr. Who etc. is being used for a 'minority' radio station.
I love my music, Radcliffe and Maconie being my favourite DJs but in the interests of fairness I think the 'silent majority' should also be considered.
