@jark Reviewing and improving #ActivityPub specification is not about coding/programming. It's about analysis and modeling. But my experience shows that it's hard to notice problems and mistakes in such documents, until you don't try to start actually using it in practise, in this case - starting to implement some application using this specification OR starting to adapt this specification, as an Analyst, for some concrete application. This way you will read every phrase, some of them - many times...
