The presentation went along like this:

• context about social media and the problems with centralized models
• some news articles about the reddit debacle and Elon being musk
• overview of the dapps framework
• the fediverse and the different apps in it
• the concept of federation and how instances work

at the end I mentioned what I considered to be the most important challenges and steps ahead for the fediverse, thinks like escalation, funding, onboarding and moderation it was fun, the class liked it, i think some were going to try mastdon, it's a start!
