I really find the image lightbox functionality irritating. I stopped reading because the words would be blacked out every time my mouse hovered over an image or even beside it. Really poor UI/UX design there.
Good start, but it's definitely lacking. English is a complex language. Using dependent clauses can modify the meaning of the independent clause. In this case, the algorithm only takes into account the independent clause, causing the summarized meaning to be significantly less than the complete meaning.

I disagree. Account creation is very important to building a client book of business. There should be two options: 1) Sign up with Facebook/Google+ or 2) Enter only first name and email address. Other information can be gathered at a later date.
The only downside to this is their pricing. The smallest license costs $5k, and it's designed to be used by 5 developers. They don't currently have a pricing model for single developers, so they're not quite Codeacademy.
