Week Two - 23 things

I keep hearing about Web 2.0, and I know that I should somehow know what the term refers to, but I don't. I read and read about it, but the concept (or whatever it is) keeps slipping through my fingers. So I asked my colleagues in the other high schools in our district to join me in going through a process called "23 things". They agreed; we set a timeline; and this is my first attempt to connect with this group through a blog.
