Right now Facebook, Youtube, and Twitter, seem to be in the role of big box store, choice from them, like variety in any big box store is becoming more limited as they bring in their brand name items.

I am glad you are paying attention. Netflix and HBO are good at this - as they push their own content very hard, and people consume it. Slowly, they will own it all too.

Webpages have become largely useless for most businesses even - as they use the social platforms instead. I like that we are starting to return to more "mom and pop" stores :)
