For me Facebook is more and more annoying. I would love to use Tumblr more but I really can't figure out how to make it grow!

Facebook- to make lots of friends and advertisement
Twitter- to share our thoughts and promotion of product
Google plus-to generate lots of promotion page
Pinterest- to pin and advertise
Youtube- PYN(Private Youtube Network) for earning money
Reddit- to explore things
