I missed it!
EDIT: I missed the scheduling article too. LOL!
Might consider having questions for the audience so the conversation goes both ways. I think keeping the topic concurrent with the goings-on at WC is a good idea. You might want to spur the convo by reading tidbits of WC or tech news. (I'm thinking the C-SPAN model. Set a topic, wait for participants, and toss in some relevant news items or points of interest)
Overall, you handled it well, Zoomba. Good job!
