I suppose if you use IG like that then sure. For me, I follow other photographers and online "zines", so my IG is full of other artists. "Influencers", celebrities, and meme accounts are banished from my feed. In turn, I only post the photos I want to be public, that I'd sell as prints or show in a gallery.
If you follow the vanity stream then you're going to see exactly that, but IG can be a totally different experience. For me, it's a fantastic source of inspiration and a way to see what other artists are doing.
Now, for me the only use FB has left is a dumping ground for my photos that the older members of my family want to see but whom are not on IG yet.
