I was on all the social media but took the plunge and deleted them all.
Some things I visited to blow time like imgur have infinite scroll in their apps but are paginated on their mobile site, so I just visit the mobile site and stop after one page. I had disabled infinite scroll in RES at first but eventually left Reddit altogether.
I no longer browse app stores, Netflix, hulu, etc. I already know what I want to watch and search for it directly.
