Instagram: Seperate accounts or one Mixed account?

Not sure what's comfortable or practical for you to do, but I have two different accounts, one that I hardly use, but it's for everything friends and family, and another one where I post mostly my digital art and gaming stuff. On the phone it's very easy to switch profiles in a click, so it's not like I have to log in and enter password every time I want to check messages and stuff.

I have three different accounts on insta: one for art, one for cosplay pictures and one for personal photos. For me personally the different accounts make sense, since not everyone is interested in my cosplay etc. but want to follow my life otherwise. And it kinda feels like having different folders for everything :D But I do understand why you are contemplating this because at some point, if you have a new interest, having yet another account for it isn't possible. I'd say go for the different accounts. If it feels weird, you can always delete "the extras" and merge them into one.
