I feel like Reddit filled gaps in times that books don't fit in as well, like a short wait at a doctors office, and it's good at that, far better than flipping through magazines from 3 years ago. The problem is it ALSO fills in the gaps where books could go and that's when it becomes a problem.
I too uninstalled RiF yesterday. Not sure where I want to go next, but I hope I read more as well. It'll probably be easier to put down my phone at night and open up my book.
