typeracer is a surprisingly fun little app. register or play as a guest, and race in typing a short paragraph against 3 other real people.
the first time you try, you’ll probably not do very well (i didn’t), as it takes a first try to get the gist of it (like, that all capitalization and punctuation has to be exactly correct, and that you can’t move your mouse to make a correction, but have to backspace). but i got better with subsequent tries, and won a few races (and got creamed by some guy who could type so much faster than me on a couple more).
after a few tries, i was getting in the mid-60s for my words per minute. not stellar, but not too bad.
have fun! report your wpm in a comment here.
