My favorite talk was called "Generations @ Work", presented at Red Hat Summit 2018.
It was about different generations in the workplace, what each grouping typically liked, disliked, was motivated by, and how they communicated differently.
I really liked it because of the content, but also because it was given by a small panel, I was a member of it. :)
Why did I propose such a talk? I usually submit technical talks to conferences, sometimes they are chosen. This year I did NOT have a technical talk selected by the Summit committee, but on a whim I had submitted this 'softball/managerial' title. It was the one that got me a ticket to Summit! You never know.
