A feature this site has allows you to see WHERE people are perusing.
Go to the bottom of the first page, and under the category 'users online' click on the link right under it that says how many users....
and it will take you to a page that shows where everybody is at. pretty cool, unless your paranoid.
I also like the ability to read all replies to any posts you make, as well as read everything new that you havent read. It is located on the top right under you username.
