Great to see that David's back in the swing:

"...my reasons for intermittent silence in the past couple of weeks have  very little to do with my numerous failings, but more to do with the  small successes and provocative challenges that have been coming my way."...

David has been busy. Lots of good links in his update today. His goal of 350,000 weblogs per annum for Virginia Community College faculty and students is mind-blowing. Good luck David. I'll be watching with much interest.
