Codefights, seems very interesting, have you done it before?

So, I'm a web designer, html, css, wordpress themes etc etc and I was busy going through the meteorjs site (as inquisitive as I am... or was it their claim to fame catchline, "Accomplish in 10 lines what would otherwise take 1000")

And I saw this article about Codefights and I went to the site and it seems like a fun way to improve your skills. I'm saying "improve" and not "learn", because it seems like you have to know something about something in order to have a fight about it.

Have any of you tried it before? Whats your experience?

By the way, if codefights was built in meteorjs, I'll definitely check out meteorjs.
