I really had a hard time getting focused on the different sites and looking for things. My two subjects of interest were high school math and southeast Texas gardening. I did not like Bloglines, couldn't quite get it to work properly for me, but I though Tchnorati was the absolute easiest to navigate. I enjoyed that one.
Edublog is interesting, and I will make a point of going back to this site and read some more of the winning blogs.
