To me, the interspersed emoticons/images detract from readability.
This is actually a great landing page! Makes me want to try the product
I've seen worse, but in my opinion, this is not a good landing page. It doesn't offer much in terms of actual, actionable information -- only marketing-speak broadsides, the layout is hard to follow, if you change the font size to make it more usable (the size the page uses is far too large), then the layout breaks further, and so on.
