Hey mate thanks for writing all that down. Gives me a few ideas - in particular how NNTP could fit in to the equation. LKML can be accessed by a usenet client at nntp.lore.kernel.org. In theory, then, it should be possible to at least read *both* LKML and ActivityPub stuff hosted at the same NNTP server. To get that working means making sure all the conversion and mapping of concepts are as clean as possible. It's a good test! Thanks again!
