This is my primary issue with Facebook and one of the reasons I stopped using it. It's fine while you have a tight social circle, but once you have several social circles on Facebook, it's very difficult to navigate those kinds of tastes, whereas in real life it's never really an issue because the people never meet.
As another poster said, Facebook is most useful as a collection of contacts, but that usefulness is constantly at war with being able to express yourself.
I know G+ gets a lot of hate but the circles aspect seemed well implemented and made compartmentalizing your different social/professional circles much easier and more transparent. I wonder why FB doesn't allow something similar?
I've been tempted to join FB in the past, not to partake in the social activities, but as a tool to manage my contacts, but I'm incredibly uncomfortable with the idea of my different social groups and my professional contacts sharing the same connections to me. If I could completely separate different circles to ensure they have absolutely no overlap or ability to see my other connections I would probably use FB.
Instagram can be made into something that is not just a mirror of your Facebook. If there's little difference between the two, you end up with the same problems - FOMO, envy, self-loathing. Instead, if you follow artists/photographers/creatives, you can find an interesting, beautiful world. Of course, there's a tension here. The more popular someone is, the more likely their feed is to devolve into brand endorsements. That commercial force corrupts.
So while its possible for instagram to be less superficial that Facebook, its a constant battle.
