Happy 15th birthday to the oldest still-living community software effort in the fediverse forest. It has been battered around over the years but the tree still stands and is currently thriving.
And Happy Birthday (69 - wahoo!) to the hippy/musician/farmer/technologist that brought all these things to the fediverse -- whether they wanted them or not:
Federated groups (public and private)
Circles/aspects
Cross-domain single sign-on
Nomadic identity
Decentralised permissions framework which can emulate any existing federated communications model from Twitter to Facebook to blogging to email. And new ones that nobody has thought of yet.
Comment controls
Quoted posts
Multicode (HTML+bbcode+Markdown)
Federated event management with participation
integrated WebDAV
Conversation containers
Directory services (centralised, decentralised, and distributed)
A large collection of contributed plugins and addons and themes (and a smaller collection of "widgets").
Shopping/ecommerce (community contribution)
Can technically federate with nearly any messaging or social protocol or project.
No artificial limits (post lengths, poll responses, attached images, etc)
And much more...
Notable feature branches:

It's been a wild ride and technically I'm retired -- but if you think that this "alternative fediverse" is going away any time soon, you must be new here.
