Horrible Widget

If you haven't heard about Dr. Horrible yet, I'd be delighted for this to be your first exposure to it. I just discovered this widget through the Dr. Horrible Twitter feed (yessss)... my teams are always looking for good examples of viral widgets and this is one of the best ones I've seen.

I will probably do a longer post about the Sing-Along Blog later, but for now explore, view, click around and see what you learn. Leave questions and comments here!
