[wiki suggestion] add "projects using hack.css" section

[sobolevn]

For now wiki is not active. Let's change it.

I suggest to add a section to show projects which are already using hack.css.
Like http://elixir-lang.moscow/

Format could be: thumbnail + link

What do you think?

I've created a page for this, you can add it there 😄

Thanks!

But for some reason there's no "edit" button:

I guess you have to allow "editing for everyone", not "collaborators only".

Oops, I think it's ok now!
