I was tickled to find out that WordPress does a yearly report. If you have the time and interest to check it out, please click here. The biggest surprise for me was that I have readers from a lot of different countries!
Update: a special reader (my husband Stewart) pointed out that the above link was only available to administrators. Here’s the link’s address: http://jetpack.me/annual-report/12585345/2011/
Hopefully it will work!
