ActivityPub and JSON-LD: Joint call between SocialCG and JSON-LD CG (April 23?)

From https://github.com/orgs/json-ld/discussions/858

> [...] on today's JSON-LD Community Group call, I proposed we schedule a
call with ActivityPub folks to discuss where JSON-LD could be improved (in
terms of documentation, examples, but especially specification language) to
help improve adoption and understanding. We'd also be happy to just hear
your stories and hear how it's going with your projects and plans -- and
where our communities might overlap and collaborate.

> [...] I thought we could start with a chat here and if there's adequate
interest we can schedule something in the coming month or so [...] Our next
one should be April 23rd: https://www.w3.org/groups/wg/json-ld/calendar/

For anyone interested in this collaboration between our two groups, please
register your interest and consider showing up to whichever meeting gets
organized!
