Newspapers are great, BUUUUUT...
Blogs are interactive.
Normally I would argue that newspapers have standards to live up to. They have to do their work to make sure what they print is correct, with coroberating evidence, and references. But that hasn't been the case aways with newspapers. But it is more the case with newspapers than it is with blogs.
Blogs and newsgroups can get away with just about anything. Throw things and against the wall, and see if they stick. Don't bother investigating just print it and move on.
There is a rush to be the first with little regard for whether it's right or not. That's what makes it scary.
