I found this funny flow chart about traditional social media. I am wondering if there is a info graphic like this but with social media of the fediverse. If this does not exist, can someone create it?
No, they are different pieces of software connected to different databases. They are run by the same company, but my understanding is Instagram is mostly about photos while Facebook has a wider variety of purposes (none of it it serves very well), eg microblogging, discussion groups, company pages, and others too.
