>"Still, I think people use Snapchat to share more inconsequential parts of their lives than we ever did on facebook"

Actually, I think this can be chalked up to the age of you and your friends. Snapchat feels very "middle school", when a status update could have been something like "I just saw a cute dog!!" -- a very low bar. Now as a 20-something a status is something I would use to say "Flying back home for a week!" -- more major events.
