I have been quiet for a couple of days as I finished up the school year and did some planning for a summer course I will be teaching the end of July/beginning of August. In the meantime, Grant Wiggins commented on the UbD Wiki post and offered up a nice bit of encouragement for those of us who are reading Understanding by Design and collaborating at the wiki, which Wikispaces has generously agreed to host ad-free. We are just getting started, so it is not too late to join up!
More tomorrow after I have rested from education for a bit.
Update, 5/30/08: Thanks to Grant for allowing UbD Educators to access his online course this year. The course is no longer available for free.
