Deleted the note of me being on App.net from my website. Interestingly that made me even more sad than deleting all the ADN apps from my devices. Maybe it's because that's content that I own and control, which makes it more personal.
There are now 2 free slots on my homescreen because I removed all my ADN apps (one slot was for my daily driver, Riposte, the other was for a folder of secondary apps). I guess I need to find some homescreen-worthy apps to fill those blank spots.
