Why is there microblogging when you could just use regular blogging software to write shorter posts?
Mastodon
Decentralised and open source social network.
I’m on a Mastodon instance with a 2,000 character limit for a reason: microblogging is only good for shitposting.
Better marketing?
I don't know
It might have a bit to do with people being tired of mainstream social media sites trying to be everything and clone each other. Snapchat was a neat novelty to me initially but they tried to do too much and lost my interest. They may want to focus on doing one things exceptionally well
Why is there #Mastodon and #Pixelfed?
I think it's a matter of familiarity with existing platforms.
- People used to microblogs can use Mastodon
- People used to image/photography apps (Instagram, VSCO) can use pixelfed
Why would I make two profiles and when do I post which image to which platform?
You don't need to make both! I just checked and you can follow Mastodon accounts on Pixelfed, and follow Pixelfed accounts on Mastodon.
So I'd recommend using and posting on whichever platform you're comfortable. If you care, you can open it on the other platform to check for formatting issues your viewers might experience.
I keep both accounts myself because I use them at different times, and while I could filter on Mastodon I like the Pixelfed app and format. Also this lets me keep up with fediverse development
I was wondering why there wasn't a federated insta. Seems there is.
Different kinds of social media. Mastodon is for microblogging (ala twitter) and Pixelfed is for picture-based posts (ala instagram).
The proper question is “why not?”.
Someone was motivated and capable enough and there you have it :)
Why they exist?
Because someone had enough motivation to create them.
Why do you need to use them?
You don't.
You are in control how the platforms are used. If mastodon can meet all your social media needs then stick to that.
Because Twitter and Instagram suck
Pixelfed is more similar to instagram and Mastodon to X (Twitter). They are different ways to access the Fediverse, Lemmy and Kbin are similar in that way (though Kbin can also use a interface similar to X).
And posts in Mastodon and Pixelfed can be seen by each other's users as long as the respective servers are federated. So choose your preferred app/interface and post freely. From what I've seen Pixelfed is used mostly by photographers.
Why would I make two profiles and when do I post which image to which platform?
When? Anytime you want.
Why: Because they have different databases they access, it's the same reason you cant log into Lemmy.world with a sh.itjust.works account.
