Graph extravaganza: Who are our “users”?

It’s Friday, so here are some interesting visitor statistics of the blog (based on the last 1580 visitors).  I meant to do this on our two year anniversary (two months ago) but better late than never.

First, where are our visitors coming from?  Primarily in the U.S. and Europe with some visits from China.

Next, what operating systems, browsers, and screen resolutions are our users using?  It appears to be Windows XP with IE.

Finally, when people reach us using a search engine, which one do they use?
