KingForADay is a chat app I've been developing after being inspired by Reddit AMA's and the Ethan chat app. The goal is to provide focused attention for a single community member each day. New chats can be initiated with only that member, but existing chats can persist.

Users can ask questions, share opinions, send pictures etc. Love to hear feedback on the pre-release!

What have you used for the backend?

Sounds like it'll be a fun social board!

haha -- this is a really clever concept. Good stuff.
