@Taneb your account is what people colloquially refer to as a "mastodon" account, yes. However, for some reason your tweets are not showing up in my timeline and so I cannot reply to them.
@psymar @Taneb standard new account things, probably
unless the post has a local copy, it won't show up in your timelines (and that won't happen unless the new account's local, or someone follows them)
This is unstable.systems, a general-purpose invite-only Mastodon instance. We'll always be pretty small, and we hope to be a comfortable instance to be on.
