@florian@owo.ff15.eu @dansup@mastodon.social Probably just native support of activitypub and the ability to use your preexisting fediverse account with it. A lot of Fediverse projects have been using Matrix for project updates and other things, so instead using a platform that you don't need to make separate accounts for is nice and more convenient. Hope it doesn't knock Matrix down in the process tho. Would be cool to see if sup eventually gets interoperability with Matrix in the future.
