I went to MagCulture's shop the other week. Lovely place for a browse. Felt like part of a change in magazine land - magazines are decreasingly a cheap thing you find almost everywhere and increasingly an expensive thing you find in only specialised places.
As David Hepworth points out, that's the remaining power of magazines, their specialness, their gloss. They're no longer the best at getting info to you, or at distributing mass culture, but they're still good at 'environment'. As Clay Shirky said, all those years ago, Brides magazine will be the last one standing.
