It is a W3C recommendation:

Prominent implementations are Mastodon ( and Pleroma ( There are several others and mobile clients as well.

The network is federated, meaning that users of different "instances" (servers) can talk to each other. Instances are run by individuals, non-profits and corporations. They can have one user or many thousands. The funding models vary. Moderation is local to each instance.

Anyone hear anything about WT.Social and ActivityPub - is WT.Social going to have open API's by supporting ActivityPub or something else, or is it going to be another walled-garden trying to compete with Facebook on its own ?

I agree, the decentralized social networking protocol of W3C is the way to go. Just like html, emails or SMS we have to get back to protocols that can be shared across platforms. Is using ActivityPub?

To be clear, I have no part in the development or the running of the network. I am just a happy Mastodon user who wishes more sites (like would federate, pool resources and multiply their reach.
