You'll only be missing out in the same sense that you're missing out if you don't go to church on Sundays or don't watch NCIS on Tuesdays. There may be commercial advantages to having accounts for your business, but there's absolutely no reason you need to personally participate in the discourse or know about the most viral tweets.
I think we've gotta step back and recognize how strange this would sound just a couple decades ago. If you talked to someone in the 70s, they'd tell you that of course mainstream media platforms are sanitized for public sensibilities; that's just what it means to be a mainstream media platform. If you want to show things that might shock and offend people, you have every right to do so, but you've gotta do it in a smaller forum. My argument is that they were right, and the past decade of nation-scale but unsanitized platforms has been an inherently unstable aberration.
