Show HN: Typeroulette, a typing test with a Twitter twist

Here is the website: http://typeroulette.com

Typeroulette is just my second programming project I am shipping and I would love some feedback from the HN community. It is a simple typing battle against the people you follow on Twitter and a fun way to practice your typing.

Everything is not quite right yet, but it would be useful to get early feedback.

Thanks
