In which I try to remember exactly what I was doing and why.
Are you gonna bring larger audience from IAPCWE here? Maybe you can ask them what topics they prefere.
From my perspective, topics that include specific people as central part of the story are tricky. If you couldn't introduce them well, it wont be as engaging if someone just didn't heard about them.
Personally, I would start with "hippies topic", everybody knows something about hippies, but from what I've seen people assume that it was grassroot movement. I would love to see just a couple posts about wtf do you mean by that, just quick overview, and then we will see if it's something worth going into.
Anyways, see ya tomorrow
