ActivityPub Conference 2019

In September of 2019 the first conference devoted to ActivityPub took place in Prague, Czech Republic, and while I did not attend it I was fortunate enough to find videos of the talks posted online. Since I think anyone who follows my stuff will be likely be interested in this, I want to give my reviews of these videos and pass along the things I find significant. Perhaps you might read this and want to check out one or more of these videos yourself. As you might have gathered from what I have written previously in this series I think ActivityPub is an important step taking back the Web from the companies that seek to control it to their own benefit while they sell us out.

If you want to see all of the videos, they can be found at https://redaktor.me/apconf/
