I read the Daily Mail most days. Well, the online version anyway. It's probably the easiest format of all the newspapers to read, it has 90% of its news on one page rather than hidden away on obscure sub-pages. I have to read it with a mental filter on though that means I take very little at face value and I'll read the more important stories again in a more rational newspaper (Telegraph, Guardian, Indy) to get a different view.
I find it a very useful intellectual exercise reading the Mail. When they're strongly against someone, or something, I deliberately become devil's advocate to see if that gives me more context. It's quite amusing how often that my devil's advocate viewpoint is similar to that shown by the Guardian or Indy's view of the subject. I do it in reverse with the Guardian when they publish a flighty left-wing puff-piece, I ask myself "What would Paul Dacre say about this?" It certainly makes the morning newspapers more interesting!
I only ever go on to the online version if someone links to it, but it seems to be full of celebrity stuff down the right hand side. When I cover a particular duty at work I deliver a copy to an elderly lady and I always catch a quick glance at the front page story. The spin they put on events is incredible; not quite Express, but getting there.
The reactions you get when you attack it, though...
