There's a ton of typos on the site, advacned, word per minute, etc.<p>As aesthetics1 mentioned, the test itself is nearly impossible to type quickly because of the jarring. In fact, the faster you type the worse this jarring is.<p>In terms of features:
It would be cool if it had immediate feedback for errors like on Typeracer :)<p>Also not a big fan of that background color on the borders. The test itself is a pretty nice gray color but the background of the overall page is kind of distracting.<p>e.g. Neighbour: it would be awesome if I could set my culture up so it uses American-isms for those words.
When lines adjust and the 'next word' moves, it is very jarring and absolutely too difficult to track. Consider fixing this. It will be an inadequate gauge of typing speed until that is worked out. Other than that, pretty good.
only major thing I noticed was the fact that all of the words seemed to shift a few times, which caused my eyes to have to refocus every time they shifted. It seemed to happen about 3 words before a new line, but I really was only focused on my 31337 typing skills :) <a href="http://imgur.com/4DEz9Yu" rel="nofollow">http://imgur.com/4DEz9Yu</a>
