# How beautiful and simple it is to store relationships in redis
# Think - I have 4 friends, you have 4 friends, but how many friends
# do we have in common? And did I tell you it handles sorted sets?
# Sorted sets are like sets but with a score. The score provides sorting 
# and ranking capabilities
