most times I come across an interesting news report in a blog, it's properly cited with a link back to the original source.
This way, I have read newspapers online, I never knew existed.
Isn't this cost-free advertising?
And won't all these backlinks increase the importance (and thereby economic value) of the original publication?
Of course, the latter effect may now be less important, due to the "nofollow" tag used by many blogs.
