I have two Instagram accounts. One just for my friends and family. And one for mindless content feed, brands, entertainment, etc. The separation has helped me reduce the mindless scrolling amazingly. I log into my friends and family account and catch up in five minutes per day. I very rarely choose to switch to the other account. Splitting into two accounts has been really healthy for me.
Yeah it's always been an option to use Instagram this way. Most people don't want to use it that way apparently, using it as a content machine instead of a traditional social network. But I know plenty of people who still do just share photos of themselves/family and only like/comment on culture stuff.
The time thing is the biggest takeaway for me, not only I spend less time overall on Instagram but I also feel way more "productive" (Weird word to use, but you know what I mean) as I actually look at every story from my friends instead of navigating through a bunch of spam from {SPORT} or {CELEBRITY}
