I set a 15 minute daily limit on Instagram. I also have my phone setup to block all non-essential apps between 7:00AM and 6:00PM on the weekdays, and I am not usually hitting my 15 Insta-minutes on those days.
I could probably reduce that to 10 and still catch up on anything from friends and family. But the extra 5 minutes is just enough time to enjoy some interesting content from the hobby-influencers I follow, yet not enough time to get sucked into the click-bait stuff.
Before setting limits I was probably at 30-60 Insta-minutes per day. Now I spend that extra time commenting on HN, which I would like to think is a more productive endeavor.
