POSSE

POSSE is an abbreviation for Publish (on your) Own Site, Syndicate Elsewhere, the practice of posting content on your own site first, then publishing copies or sharing links to third parties (like social media silos) with original post links to provide viewers a path to directly interacting with your content.

Nice that we have a name now for something that's pretty much standard and common practice. Not that we necessarily needed a name, but it's still nice to have one.

The idea is about 10 years old. At least that's when I first heard about it, with relation to RSS. It may go back earlier.

Edit: confirmed by the "See Also" section at the end of TFA.
