On the Indiewebcamp wiki, Tantek cited this as the first example of a POSSE between Known, Ello, and Twitter.
Although technically it's a POSSEDOSROS: post on site, syndicate elsewhere, delete on site, repost on site.
This status update is actually a recreation of the original update, which was automatically syndicated to Twitter and then manually copied to ello (dropping the #ello hashtag). Then I mistakenly deleted it. Oops. So I reposted at the same URL, and recreated the "Also on Twitter" link.
The like and reshare from Jon Pincus were on Twitter, and came automagically via brid.gy.
