Pixelfed is a federated photo sharing platform similar to instagram, signing in with Mastodon lets you carry over who you're following on Mastodon.
So I wouldn't say it's too important, but I thought it belonged here.
I think it's also worth mentioning here that, since both pixelfed and mastodon belong to the fediverse, you can follow pixelfed users from mastodon and vice versa and see each others posts. :)
That's why the whole carrying over the people you follow stuff is a thing.
Yeah. Even though I’ll probably never use Pixelfed (I don’t use Instagram, either, or anything like it) I still acknowledge that’s a pretty cool feature.
And this is where federation and interoperability becomes nice imo, because one doesn't have to use pixelfed and can still get content from Pixelfed in their Mastodon feed, if they want to.
Say someone would like to see the content of just a few Pixelfed users, but doesn't want to create an own Pixelfed account just for that, one can just to follow those specific Pixelfed users with their Mastodon account to see the Pixelfed posts in their Mastodon home timeline.
