Few years ago, in order to interact with the audience, I started a Cisco Live presentation involving some Spanning Tree design with three questions:
- Who hates the Spanning Tree Protocol (STP)?
This one is easy. You could sell ice blocks to an Eskimo based on the ubiquitous hatred for STP. Here, I got a good 90% of the hands in the air.
- Who has a good understanding of STP?
More personal question, but this is Cisco Live, with networking experts all over the place. Some 60-70% hands were raised.
- Who thinks that the root bridge can block a port?
Audience stunned! Some were shaking their head, with a negative expression, the others suddenly realized they had an urgent email to check or looked away. Among the more than 100 attendees, only one person in the front was frantically raising his hand. Too bad for him, there was no prize.
I drew two conclusions from this:
- First, giving the impression that you’re thinking your audience is made of idiots is not good for your session evaluation.
