I am against the closure of radio6! At the moment I almost exclusively listen to radio 6 to learn about new music.
The majority of the output from Radio 1 could be covered on a commercial radio station. Apart from John Peel and a few other shows, radio 1 has a poor record of producing cutting edge music shows. Although I understand why Chris Moyles is on radio1, I don't see how his show is consistent with the BBC's new strategic principles. It is difficult to believe that the specialist shows on radio6 could transfer to radio1 and not be diluted and changed.
Many of the shows on radio6 could not survive in the commercial sector, however they do enhance the culture of the UK. New music is also important to the economy, for example by people downloading music and going to gigs, so it useful if there is national station that informs people of new sounds.
Please don't close radio6.
I think you will be doing more than "Reducing the BBC offer in pop music radio by closing 6 Music" Radio 6 puts out mostly specialsed innovative music, rather than just "pop music". The station is not a clone of radio 1. It provides musc that is not available in the commercial sector.
Although I occasionally use lastfm, there is no substitute for a knowlegable expert presenting a show.
Please don't shut 6music down.
