This Forbes Article is great!  I think one of the biggest takeaways is this line "...the Internet is still about searching for information.  Indeed out of the top five sites most trafficked by U.S. visitors...four are portals (search engines) to other Web sites."
The Internet is about search.  That's what people are doing.  While email is still the most popular activity, the proof of the importance of search is in the rankings (make sure to check out the slides that compare the Top 20 Sites of 2005 to the Top 20 Sites of 2008 --- so amazing how quick we forget 'cool' destination sites, does anyone even remember Gorilla Nation Media from 2005?).

The one regret I have of the article is the fact that the author never did tie blogs into the search world or the idea to blog for SEO.  And the mention of blogging is grouped into social networks and forums.  While all of these do create the so called "interaction" the idea that businesses only can utilize blogs to monitor the chatter is an understatement --- what about taking the next step and implementing their own business blogging strategy?
