Technorati

I explored the Top 100 blogs,voted by authority and went into site 4-Engadget which was about photoshop for videos. It was voted number 5 by fans.
Jennifer Garner was number 4 in the top searches.
There were 7,600 results for Learning 2.0.
Will reserve judgement until I get more time to go back in but the tutorials I went into about Technorati were good
