Blue, i'm fairly new to it. But it's really just a social media app. The big factor about it is that all pics posted delete after 24hrs. But it mostly a fun way to share photos and messages with people.
I would love to see more providers do snap. It can even be profitable doing a premium route and charging like $20 a month. Sign up 100 people and you're looking at $2K just by taking a few pics a day.
