I didn't find this exercise particularly interesting as I am not the into blogs. However it was interesting to delve into this huge world and see the vast amount of activities and information out there. For people that are interested in Blogs I can see how technorati could be an amazing tool and I was very impressed by their website, very easy to use and filled with information.
On technorati I could not find the search box with the 3 drop down options, just a simple search line. I searched for web 2.0 on this but didn't come up with anything particually interesting or relevent.
