Cross-posting is the social media practice of syndicating or placing the same content, possibly slightly modified, on numerous different websites.
For example, an organisation will have a blog post on its own website that it copies to websites of other places with similar objectives or to silos such as LinkedIn where a larger audience may see it. This is essentially POSSE without the name, practised by people who don’t know that they are being a little bit indieweb in doing so. It is often accompanied by an apology, such as “Apologies for cross-posting”. (The apologies are ostensibly meant for people who are following them on multiple platforms and thus seeing the same message multiple times.)

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.
Why
Let your friends read your posts, their way. POSSE lets your friends keep using whatever they use to read your stuff (e.g. social media silos like Instagram, Tumblr, Twitter, Neocities, etc.).
Stay in touch with friends now, not some theoretical future. POSSE is about staying in touch with current friends now, rather than the potential of staying in touch with friends in the future.
Friends are more important than federation. By focusing on relationships that matter to people rather than architectural ideals, from a human perspective, POSSE is more important than federation. Additionally, if federated approaches take a POSSE approach first, they will likely get better adoption (everyone wants to stay in touch with their friends), and thereby more rapidly approach that federated future.
POSSE is beyond blogging. It’s a key part of why and how the IndieWeb movement is different from just “everyone blog on their own site”, and also different from “everyone just install and run (YourFavoriteSocialSoftware)” etc. monoculture solutions.

PESOS
PESOS is an acronym for Publish Elsewhere, Syndicate (to your) Own Site. It’s a syndication model where publishing starts by posting to a 3rd party service, then using infrastructure (e.g. feeds, Micropub, webhooks) to create an archive copy on your site.
The opposite (and preferable) approach is POSSE, whereby a user publishes original content to their own site, and then syndicates copies to 3rd party services, preferably with perma(short)links back to the originals on their own site.
