And why must I create a new ‘article’ to make a thread and not a post - which I think makes a new microblog.
I’m coming from a Mastodon POV, I run my own instance and have a pretty good idea (I think) about how federation works. The way ActivityPub is used is close enough to be familiar but also… not; very uncanny valley.
Additionally, if upvotes are favourites, what are downvotes? and how are they federated?
Your account can be followed by a Mastodon account. Any Mastodon/Misskey/Pleroma/etc. follower will see on her/his feed not only all your posts and comments, but also anything you boosts. Boosts is retweet/reblog.
