The first time I used it. Very much unlike Twitter who, back when it was first introduced, I liked a lot, it was great place to chat with strangers and meet some real cool people. In the end I also quit using Twitter (a few years before it became X) but not for the same reasons: the atmosphere had become too toxic and way too hate/drama-focused to my taste. Facebook was nasty & bad for (my) mental health since its inception.
