I gave this talk[0] a few weeks ago at MyData 2018 about ActivityPub. Dmitry was going to come and talk about Solid on the same panel, but couldn't make it last minute. So I spoke a bit about Solid at the end too, and compared and contrasted.

Kim Hamilton Duffy gave an illuminating talk right before me about "Decentralized Identifiers and Self Sovereign Identity Standards"[1]

lmk if any feedback or questions
