It seems that I have been eavesdropping a lot lately, but here is something I heard today:
"All the speakers were male, so there was no possibility of anyone having been included just for diversity reasons."
That's so good to know. I hate it when there are token women in a session and you have to wonder what they are doing there because there is the added complexity of having to figure out if they were invited because they have interesting things to say or whether the session had to include at least one woman. Everything is much more straightforward when it's just a bunch of deserving guys who were invited because they are all brilliant and articulate.
