I use Google Analytics to get a sense of viewership, how people are finding the blog, how many visitors per day, what postings are most popular in terms of views, etc...
I also get information about location of viewers. For example: I can tell that Julie has viewed the site due to number of visits by somebody in Indianapolis.
The big mystery is that I seem to have regular visitors from San Diego, CA and Mount Vernon, NY.
Is it somebody that I know? Care to make yourself known? If so, drop a comment to this posting.
