Holy time management, Batman! I'm going to get a bad rep at OSCON for running over time (last year, though, it was due to a late start).
Basically, I was pacing myself for a 60 minute session, not the 35 they give you. Way too many slides, too much intro, kept me from the cool stuff at the end of the session. Also, there were lots of good, informed questions.
My goal for the Tapestry session, later today, is to run under. But I don't see that happening.
