Items 1-4
I created my blog (item 3) on May 14, 2011.
I then looked at some blogs of interest to me (item 1), and added a few to my blog list.
I read the article about Technorati and checked out the web site (item 2) on June 6, 2011. There are blogs on pretty much everything.
I'm continuing to follow the blogs of my co-workers (item 4).
