IS facebook loosing popularity?

[GAVIN]

I agree that Facebook is losing its popularity. Instagram, if you ask me, is taking over the niche Facebook fills in the Internet. It's not very noticeable, both Facebook's decline in popularity and Instagram's advancement toward most popular social media site; what I notice is a lot of my Facebook friends are joining Instagram (this is where my theory stems from). Also, Vine is dead as a social media, if it even was. Twitter is on its downfall too, but it will take a while (in my opinion) to become irrelevant. Choose me as best answer and tell me what you think about Twitter, Instagram, and Vine (what I think about them). Thanks!
