Gee I can't imagine why the snapchat ethos of burying undocumented but core features deep within the app until they are unlocked by an errant gesture wouldn't be more popular? Time and time again, I question why I would want to be told how to use an app when I could have so much fun making a game of discovery out of it. Really it's probably for the best that these things are provided only to the most prolific and zealous users though. Maybe some day I will be lucky enough to fall on the right side of the A/B testing line and get the good stuff.
