This link is missing a number of things:
- 2009 Lorea started implementing OStatus for Elgg
- 2010 Lorea was the first software to implement 100% of OStatus
- 2010 GNU consensus was created to gather federated and P2P social networking under a GNU umbrella
- 2019 First APconf in Prague created the SocialHub
- 2020, October 19 @pukkamustard proposed the Fediverse Enhancement Proposals (FEP-a4ed)
And probably other things…
