I've been reading some of the posts on this thread since the changes at Smooth. It does seem like there are two types of listener; the type that just has radio on as background/wallpaper who aren't bothered about who's presenting and the lack of variety of music being played. Then there's the other type (like myself) who really appreciates radio as a foreground (rather than a background) and who really cares about the music being played, the programme content and the presenting style, i.e. what the presenter brings to a show in terms of their musical knowledge, enthusiasm and their ability to connect and interact with the listener.
What I find quite puzzling is that it appears the majority of listeners now who seem to affect RAJAR figures seem to be the 'wallpaper' type of listener. Maybe the more discerning listener is becoming a thing of the past, (at least where commercial radio is concerned), a real pity if that's the case.
