To me social media is;
Facebook: People overselling their lives to friends they had 20 years ago in high school. Basically a high school reunion, but every day.
Instagram; Same as Facebook, but with pictures
Twitter: A place to fight with strangers using opinions as facts.
But I do find that Twitter holds the most up to date news and information, especially when it comes to arenas that I follow the most, sports and movie/tv. I gave up Facebook quite a few years ago.
As far as the Uni/Disney Twitter rivalry goes, well, it’s actually just one sided. Idk if it’s Disney themselves, or their social media management team, but they’re very stiff in their tweets. Just plain information, no real fun. That’s not a bad thing. But Universal just doesn’t take themselves seriously and it shows in whoever runs their social media team. I prefer that type of account, but YMMV
