Yes, I enjoy reading blogs a lot. But I think that one has to be cautious what to read. Blogs can be *sponsored* by a company, they can also be set up as part of a marketing / publicity campaign - there have been such nasty things in the past.

I can only answer your last question indirectly.

Bad news are actually "good" news. And those type of news which satisfy primal instincts - because they are mass compatible:

violence
murder
sex, porn
something that makes you feel superior to others (a fallen star for example: drug abuse, a car accident, a shaved head - hello to Lindsay and Britney!)
tax increases (why, damn it?)
