Then you can follow other accounts, on the same server or on other servers (more on federation later). Your can allow anyone to follow you, or approve each follower.
For federation, follows and approvals are passed between servers and public events are federated between servers running our software. Over time, we hope to use #ActivityPub fully to trade data with other event software.
And some things we didn't mention! Many rough edges and a lot to do, but if you are interested or just want to let us know what you think of the idea get in touch. There is more on our website: https://www.theoccasionoctopus.net/
Then you can go to discover, and browse all the events people you follow are publishing. If you like one ... you've just discovered a new upcoming event! You can add it to your set of events to recommend to your followers.
