Blogging as a News Source

In an article from the BCC, http://news.bbc.co.uk/2/hi/technology/4330690.stm
the arguement is made that news from blogs have proven themselves worthy:

They have proved their worth as news sources in recent times, perhaps most notably following Hurricane Katrina.

Pete Clifton, editor of the BBC News website, thinks blogs have a valuable role to play because they embrace the value of what people know, and what they are saying. He further went on to say he doesn't think blogs will takeover sources of news journalism like the BBC, but could be complimentary.

AOL bought Weblogs, Inc. which indicates that they see $$$ from it.

One criticism made in the article was the blurring of professional news with that from blogs which is happening on Yahoo News.
