Interesting that "Small - Brainstorming" is marked as a bad meeting flavour.

I mean, for starters, I'm not the biggest fan of brainstorming anyway: I tend to be more creative on my own, and then we can come together to compare/refine ideas. A lot of people I've worked with are like this.

But, to me at any rate, if you absolutely must brainstorm then "Medium - Brainstorming" and "Large - Brainstorming" seem like way worse flavours than "Small - Brainstorming". I and too many other people I know tend to withdraw rather than contribute when any kind of meeting gets too large, and especially if it's a brainstorming meeting.

Right now I am struggling to think of anything worse.

Otherwise, agree with everything else in the presentation, and practice most of it as well.
