Shel: I've been chewing over for a couple of days what's bugging me about this whole idea. I think it's this: will all companies benefit? Will hardware stores and supermarkets really benefit? I work for a charity. Our supporters are mainly over 50. I know there are a lot of silver surfers, but there are a lot of people who aren't. Will a blog reach them? If you don't think all companies will benefit, please say which will.
