Smoke Signal is an Events & RSVP system built on top of ATProtocol https://smokesignal.events/
Developer Nick Gerakines https://bsky.app/profile/ngerakines.me has an extensive background in social platforms:
> I started Smoke Signal because users should have ownership and control of the content that they create. Having built sites like del.icio.us at Yahoo in the Social Search group and contributed to early web 2.0 sites like upcoming.org and Flickr, I firmly believe that there is sustainable demand for online services that are both functional and not harmful.
Nick has written some great blog posts on this:
