I am most definitely wishing I was going to Agile 2008. I have seen on the Yahoo groups and on the web page that there will be many people there that I would love to listen to and learn from. I saw that someone is posting constant updates from there and I will certainly be following that.

I'll be watching the Twitterers as well. To the people I know who are going, I'll be there in spirit!
