How is this any different than hosting content on a corresponding provider. Videos on Youtube and Vimeo,resume on LinkedIn, Portfolio on any blogging platform,or just simply using Facebook Pages?

I can understand that people have the freedom of putting anything on your site (to a point), but it still requires work to create a new site and having a knowledge of html and css at the minimum.

The cost is cheap $10 a day, but it is still more than the free providers on those mentioned.
