I am not a tech savvy person at all. Came to computers late in life, don't know how they work under the hood. I didn't come here from some other social media because I didn't use social media then. Heard about Mastodon in a news article, and was curious.
Since you don't have to sign up first in order to explore, I just lurked and explored for a few months, cautiously, since I'd heard bad things about social media in general. But I liked what I found, and finally decided to sign up.
I had jumped around exploring without ever noticing there are different servers. So when I decided to click on "sign-up", it just signed me onto whatever server I happened to be reading a post on at the moment. So sheer chance. But I'm happy enough with where I ended up.
