Additionally, there’s the usability hurdle of interacting with non-home instances from outside mastodon. If I pull up someone’s blog and click the little mastodon social media icon, it may very well link to mastodon.world. If my home instance is mastodon.social, now I have to launch into my own server, search up the account, and then begin interacting.
It’s trivial to do but it is an extra step, but for your less-tech-literate friends and family it can be a point of confusion. Mastodon handles federation great in-ecosystem, but the broader web is still going to treat each instance as a different site.
404media is doing excellent work on tracking the non-consentual porn market and technology. Unfortunately, you don’t really see the larger, more mainstream outlets giving it the same attention beyond its effect on Taylor Swift.
