So I don't know if it's an amaroq thing or an octodon thing, but be aware that your toots currently don't appear in the federated timeline by default peeps...(you have to manually change the visibility setting from unlisted to public...)
@tcql Ahh, right. Must be an Amaroq thing then! ;-)
@orielle default on the web is public
