A lot of the accounts you follow and interact with on here are not Mastodon accounts!
For example, @theatticdwellers is a PeerTube account, @Iancylkowski is a Pixelfed account, @rstv is an OwnCast account.
There are dozens of different server types on here, not just Mastodon servers. When you talk about this place, it's not enough to call it "Mastodon", because it's more than just that.
That's why people call this place "The Fediverse", because that name covers all server types. 
@zalintyre @theatticdwellers @Iancylkowski @rstv
No, you can't run a server of one type as another type.
But people on different types of servers can follow each other and interact with each other seamlessly. See my latest post:
Attached: 2 images If there's the same conversation shown on different kinds of Fediverse server, each server type will display it in its own format. For example: In the attached images, you can see a conversation thread in the replies to a PeerTube video post. On Mastodon it will look like a Masto thread, but on PeerTube it will look like comments below the video. They are both the same thread! It's just displayed differently depending on which kind of server you're looking at it from. #FediTips #Fediverse
@zalintyre It doesn't bring any advantages for interaction, but if you want more features and better view in terms of photos, then an additional #Pixelfed account would make sense, because Pixelfed is specialised on pictures.
