After toiling away at this for a few months, I'm releasing two new Go projects for the fediverse today:
longdistance, a JSON-LD processor.
pana, an ActivityStreams library built on longdistance.
I built these projects with the hope to make it easier for folks to get started building on the fediverse themselves. You can read a bit about this on my blog.
(If you happen to have computer touchers in your followers, I would appreciate a boost.)
