Hah, love the change in shade of blue on the graph to match facebook's - interesting touch.
I'm not sure why andreyf was being down-modded, the graph on the original blog post at http://bret.appspot.com/entry/tornado-web-server uses a subtly different shade of blue. This is a clear attention to details that is worthy of at least a small note in a community such as ours :-)
Yeah, I should have explained the context of that remark better. Thanks for fishing me out of downvote land :)
