I've done something similar with my Android phone, and it's worked out decently. One problem I encountered though - I spent a lot of time on Reddit, and would check it subconsciously, so I deleted it. Now I find that I'm using Google Now, the left swipe off the home screen. In effect I took the attention from Reddit and gave it to Google. I'm not convinced that was a worthwhile trade. Given I can't delete Google Now, maybe having Reddit on my phone was serving a purpose I didn't realize. Maybe there's an app that will minimize the subconscious attention blast radius. Something that I'll still check but will minimize the time I spend there.
