For newcomers, continued:
People here value authenticity, quirkiness and idiosyncrasies more than performance. Rage-baiting, "influencer"-ing, trolling, punching down, and other inauthentic, shitty behaviors tend to get you unfollowed and ignored since there is no algorithm to game, no advertisers to impress, no sponsorships to try to drum up.
Want to get seen and have interactions with real people? Be one! Share cool stuff that informs or entertains. Even if you think it is just your own quirky interest, you'll probably find others who will appreciate it. Or just post cat pics.
Politics, controversies and arguments about any subject are fine, of course, but unlike eXTwitter or Facebook (and, I'm presuming, Blue Sky and Threads), where being a dick gets you amplified by the engagement algorithm, here you just get ignored or blocked.
In that vein, I'd recommend observing the culture here for a bit before venturing into any of the hot-button topics.
