Seems really slow and unresponsive in Chrome on OS X.

1. The map started out in Dublin, which doesn't help me as I'm in New York. It's really hard to find out what traffic is like there - I can't even see the eastern seaboard under all the circles, so it's hard to zoom.

2. Speaking of circles, I have no idea what they indicate. Accidents? Tweets about being stuck in traffic?

3. I'm sure that Mary Raftery was a great person, but I don't care. What does she have to do with traffic?

4. How do I contact you? The site doesn't appear to have any way to provide feedback.
