This isn't an effective analogy. The Internet is one big concrete square. YouTube and Facebook occupy one part of this big concrete square. You're free to occupy your own section of the square, too. The fact that YouTube and Facebook are so popular isn't because their portion of the square is any better than others - it's because the content they're offering is better (at least in the eyes of most people). There's nothing inherently better about YouTube or Facebook's portion of the square, their popularity is the product of the content they offer.
