Des is very good, great charisma and a world of knowledge, irreplaceable and we have no one quite like him in NZ.
But... Radio is old fashioned, for a new audience it was difficult to follow. As a punter who enjoyed his broadcast's I was frustrated when i missed a good interview, it wasn't quickly uploaded or accessible, if it was uploaded it never had bookmarks for key interviews and information.
I hope he can look into setting up a remote studio and start his own podcast, he doesn't need the TAB or the Radio to do things better than before.
