Hi Nick, I am fine with no slides but not with "no detailed preparation". Ok some people can make it work but I have seen it fall flat too many times.
If I am paying in to a conference I want to know the speakers have worked on preparing and condensing an informative, engaging (and bonus entertaining) talk.

Heh.
The usual reply I get from events (regardless on how good the pitch is) is "We would love to have you speak. A speaking slot comes with the Bronze to Platinum sponsorship package. Let me know how you wish to pay".
It is no wonder so many talks are uninspiring or simply product pitches :(

Interesting personal account of life without managers. Thank you.
Do you have any insight into the business results of it?
