First of all, I don't mean this post as a complaint, maybe more of a warning?
There is teenagers on the fediverse. Most of them don't share their age, for hopefully obvious reasons.
I'd say that a lot of the accounts which do a lot of posting/commenting are run by teenagers
because most adults probably wouldn't have the time for that much posting.
While the young people of this generation are generally useless when it comes to something more complicated than microsoft word, the people who are good at technology, usually are very good at it.
most of my friends (most of which don't know the difference between a laptop and a desktop) could understand the fediverse as a concept perfectly when I explained it to them irl.
So, if you're in a really stupid argument with someone, try to remember that there is a small chance they are 14.
