Jeff Utecht was the IT Coordinator at YIS before I arrived and has been my mentor, of a sort, ever since. I follow his blog, The Thinking Stick (http://www.thethinkingstick.com/), twitter (jutecht), and even got to meet and talk at one of the lounges at ISTE 2009. He's written a book about the Web 2.0 and education which has some interesting stuff in it. It's available on amazon or lulu.com, and he's offering a discount on his blog.
