folks, please, please, please (if you use Mastodon just pretend these words are formatted with emphasis) don’t compromise on your AS2 vocab usage just to make posts look nice in Mastodon right now.
you’re cheating yourselves out of richer integration with other software, like Pleroma, Plume, Read.as, Hubzilla, Friendica, Osada, and PixelFed, who will be more than happy to process your AS2 vocab correctly.
instead, ask for Mastodon to improve their support of non-Note objects.
if you send an blog post as an Article, Pleroma, Plume and Read.as can be used as a social reader. if you send it as a Note, well… it kind of sucks.
