Could someone explain this difference on Mastodon posts?

Most of us are limited to posts containing 500 characters, which I think is good, while others seem to be able to post ‘articles’ with no apperent limit.

Why?

#mastodon

@perjakobsen It’s dependent on the server their account is hosted on. 500 is default. I some times envy the longer posts, but I think restraint is a good thing for this medium.

@perjakobsen Mastodon is just an(other) implementation of ActivityPub protocol and the ActivityStreams language.

On that level there is no limitation. But mastodon has one.

This is the cool thing about #feediverse you not could only use your mastodon user to subscribe to other mastodon servers users, but also f.e. follow a peertube or friendica account. As f.e. friendica has its root in beeing a (micro)blogging service, it might have no limit.
