This site has a 'site meter' ( to the left or below )
http://www.sitemeter.com/?a=stats&s=s16ohffs
And if you click on it you can see the normal stuff ( Last few visitors, how they got here, where they're from e.t.c. )
But, towards the bottom right of the page there are some other links:

I'm surprised to see so many people that visit have Linux. Or are visiting from work or school.
Also nice to see that alot of you don't use IE.

Don't know if you found that interesting, but I did when I saw it.

P.S Added some of the charts as attachments.
