The landing page for this site could stand to be improved, especially if it's target is absolute beginners.

* The instructions provided are very Unix specific and assume a reasonable level of familiarity with the command line. Lots of beginners are probably on Windows and not used to using the shell. Much as devs shun them, installable GUI clients have their advantages in this area.

* The language used on the first page is still fairly technical, "test suite" for example.

* How it works is not made clear, "practice problems" is only mentioned once at the top of the page in a hard to read colour and small font.

In fact, the article ends in mostly the same sentiment expressed by the site's creator:

"But she would like to raise money to pay people to improve it. For example, she admits that the site is a bit lack in the usability department. “It’s hard to tell what it is just by looking at it,” she says. “It’s remarkable to me that people have figured out how to use it.”"

I'm also a little unclear on the why the site leans in a fairly technical direction. I think I'm going to try it out later so that I can get a feel for what's actually required to get going. I really like evaluating these sites to find tools to integrate into our(my company's) training program.
