PL, but I had internet friends during my teen years and it ended up keeping me from socializing with the people around me. Not going to give my exact age on KF, but I'm guessing by you being an adult zoomer that we are around the same age, so this is coming from a person in a somewhat similar situation.
While I still like all of them as people and value the companionship we had over the years, if I could go back and do it again I'd try to make real life friends instead.
Plus, you're more likely to bump into absolute psychos on the internet. I mean, the entire point of this website is documenting and laughing at said psychos. Surprised someone on KF of all places would want internet friends, but I don't mean that in a mean or mocking way.

@SandyCat said, if you need to have some social interaction online ( I'm not talking full blown friendships) vidya can be a good way to find some people you can play games with regularly and occasionally send something funny to. It wasn't a full blown friendship or anything, but I used to play Scrabble regularly with someone online and we'd sometimes send memes and wish each other Merry Christmas. That was about the end of it, but it was nice having someone who would be online to play at the same time I was, and who I knew wouldn't flake out in a game or flip out if they were losing.
