Google-Analytics.com?

I noticed this morning while blogging that HTTP activity was going on between my copy of Firefox and Google-Analytics.com (I use the multi-tabbed interface, so I couldn't catch which of the 15 tabbed web pages was making the request). Wondering what this was and getting a 404 error when trying to browse to that URL, I - ahem - Googled it, finding this Search Engine Watch article. Interesting.

I still haven't figure out what it's for - my guess is something with Blogger, which I use and of course, which Google now owns.
