In conversation with Tantek Çelik, I asked if a double entendre meaning to POSSE was originally intended when it was coined?
POSSE is an abbreviation for Publish (on your) Own Site, Syndicate Elsewhere (or Everywhere), a content publishing model that starts with posting content on your own domain first, then syndicating out copies to 3rd party services with permashortlinks back to the original on your site.
When I originally heard about POSSE, I considered the original post on my own site as the Sheriff or “leader” and the ensuing syndicated copies as the (literal and figurative) traditional posse which follows along behind it adding ideas, conversation, and help in accomplishing the original post’s mission.

If that second meaning didn’t exist before, it does now…
hah – second meaning for POSSE, like there’s only one Sheriff (original post) but many deputies?

Sheriff of Content
I like the idea of the original being the “sheriff” 🙂
Missing Icons · Issue #38 · dshanske/syndication-links https://github.com/dshanske/syndication-links/issues/38
I noticed that there doesn’t seem to be an icon (or it’s blank) within syndication links for SoundCloud. It doesn’t display the default “share” icon, but shows up as a blank white spot. Maybe a typo in ‘syndication-links/includes/class-syn-meta.php’ as ‘soundcloud.com’ => ‘cloud’,instead of ‘soundcloud’?
Additionally, Ghost and Mailto are explicitly supported in the code, but use the default share icon rather than native icons (perhaps because Ghost doesn’t have none?)
