I wish that I would have caught this session because one presenter (I won't say who) kept yelling out "squirrel" during her session at AFP 2010, which I found extremely distracting...not that she did not have some valuable information in her presentation, but still, the squirrel bit was annoying in my opinion. I have a feeling that yours was more effective. On the metrics side, I agree with the previous comment and some points you have made before. Keeping follower counts, comments, etc in mind is all well and good, but engagement ratios, share of voice, and other relative measures are better measures of effectiveness, success, etc.
