thejerz feedback is spot on.
This is how my visit went right now:
i clicked through the site and immediately started scrolling through images. and didnt even know there was anything else.
came back to hn opened comments and saw the practice engine mentioned. went back to the site looking to checkout the practice engine, noticed it mentioned as a single line on top. clicked through but all I found was a page to pay.
My thoughts: i m intrigued by the practice engine but with no demo, no convincing plus a limited course offering, im going on blind faith. the value proposition is hidden. images are overwhelming and i lose all my attention to them.
hope this helps. good luck.
