But the link to the playground is on page 1, the home page, and not page 12? So your whole argument is moot, since it seems the Pony people obeyed at least this part of your interface design dogma.

Or, in other words, "you could not be more wrong if you tried :)".

The issue here was that page 2 was linked in the title, so everyone was getting to page 2, and not clicking back to page 1, where the playground was, and instead clicking forward and getting lost.

And all that aside, as another commenter said, even if the playground was hidden behind the most fiendish of mazes -- perhaps not every programming language is interested in attracting the kind of people who think every corner of the universe must mirror Amazon's approach to "sales".
