Reason looks back over the best and the worst of the past decade, which really isn't over yet. The blogosphere is listed both as one of the best and one of the worst developments. But overall I agree with the following:

There are few positive things about that horrid decade that just past, but the rise of blogosphere surely qualifies as one of them. Anything that draws power away from those precious old media types, who for so many years held a monopoly on what and how stories were covered, should be celebrated. Looking back on the media coverage of Iraq, Bush, and the 9/11 attacks, enterprising bloggers of all political stripes helped fact-check the dubious and lazy stories provided by our endangered comrades in big media.

The best bloggers are unsurpassed in giving us the full story behind the news, not just the MSM version.
