I notice from reading other blogs that some of them are nothing more than glorified advertisements, selling all sorts of products and services under the guise of a blog.
Personally, I find this quite outrageous. I mean, let's say, for example, I was organising a charity fundraising ball on 14 November 2008 at the Holiday Inn, Seaton Burn, there's no way I'd use my blog as a cheap way of advertising this fantastic event. Even if it is for Guide Dogs, and even if it does promise to be a brilliant night out, with a 3-course dinner, live band and disco until 1am. I just wouldn't stoop so low. Other, less worthy sites will even blatantly try to sell their wares by saying things like "Tickets are £35, tables seat 8 and you can get your tickets by emailing email@example.com" I don't know how they have the front.
