In the early days of social media, there was a lot more interoperability. You could auto post to Twitter from Facebook, Instagram could post to Twitter, subscribe to subreddits via rss etc.
Social media companies wanted to grow their share and one way to do that was make it easy for people to post from one platform to many.
But with the rise of social externalities (bots, spam, political ops) and the plateauing of growth, lots of these companies closed down their APIs. YouTuber Tom Scott talks about this era some here: https://youtu.be/BxV14h0kFs0
One of the major things that attracts me to the fediverse is the renewal of interoperable promise.
A tool that a lot of people used back in the day and now less so due to the lack of api support is “post once, publish everywhere” tools.
Does anybody know of such a tool for the fediverse?
The use case I see: I post some pictures to my pixelfed account, those automatically get posted to my mastodon account, and if they have certain hashtags or something then get posted to relevant lemmy communities.
I think one thing the recent “alternative frontends for lemmy” shows is the universality of a lot of content for different user interfaces.
Different frontends serve different use cases (following people on mastodon versus mutual friendships on friendica versus following subject matter groups on lemmy) and their user interfaces create different kinds of community (thousands of followers on mastodon in a porous discourse versus tighter private communities focused on specific subjects on lemmy).
It makes sense to decouple to a degree content and frontend. I think having the ability to post once distribute to many different frontends and community types is powerful and something unfederated media simply can’t provide.
