A Question for you

Here is where I would like some help.  What social media do you use?  Facebook, Twitter, Snap Chat or what else is there that keeps your interest?  Pinterest?  If you are a business which sites have been the best for your advertising?  If you are a normal internet surfer which site has given you ads that you have responded to?  I understand the growing popularity of social media and would like to know where best to spend my time.  Anyone who responds to this gets $10 off their next transaction with me.
