It is done.

Well, I would not say it was an overwhelming success, but my talk inspired a great deal of questions, clarified a number of issues about the work in my mind and taught me that I think from now on I will work on giving blackboard talks instead of using slides. Admittedly, I went big giving a blackboard talk on new work, which was probably too risky. Hopefully there are those out there who measure success with degree of difficulty factored in to their assessment.
