This has been asked before and Ive scrolled through countless explanations but since I am not so good with all these terms Id appreciate if anyone could explain to me what mastodon is in a very simple way. Ive heard it's similar to twitter…

I recently discovered my husband has a mastodon account. He formerly had an NSFW Reddit profile and was in communities like slut social, hot wife, cuckolds, etc. I am curious if mastodon has similar communities if that’s how it works.
