Related to another Reddit app, but not RIF:
The Relay for Reddit dev (u/dbrady) is bravely working on Relay. I got an update yesterday. The changelog said "further reduce API calls". I think he actually wants to make it a paid app, which I'd gladly pay for.
I hate the Reddit change as much as the next guy, but if the Relay dev can actually make a profit from it that'd be awesome. The app cost a one-time $4 or something, which I'm sure he never made bank with. Having like $3-5/month for it would probably be sustainable.
