For research purposes, this site uses Google Analytics to collect aggregate information about, e.g., how often the site is used and what links are followed from it. We do not collect personally identifiable information, but if you have a Gmail account or have ever Googled yourself from your own computer, then, despite their assurances to the contrary, Google does collect such information. We recommend that you use AdBlock Plus, Ghostery, NoScript, and/or Privoxy to protect your browsing privacy. The first two are really easy to install and use; the last two take a bit more effort to whitelist sites you trust. (You might also consider the tracking-free DuckDuckGo search engine.)

We do collect your IP address. If you have a fixed IP address, this is personally identifying information. (If you don't know what a "fixed IP address" is, this almost certainly doesn't apply to you.)
