You basically "tag" a post with a hidden one-pixel graphic that links back to the ljtoys server, which looks at IP addresses to work out how many hits a post gets, and even funky things like ljusername, whether the person was looking at their friendslist or directly clicked on the post, and what country they were in at the time. It's surreptitious data gathering, which bothers some people, but I admit I just find it kinda nifty.
(it can be blocked/fooled, by people paranoid enough to configure their browsers to block such things. Personally, I work on the assumption that if I'm online, I have no privacy; someone somewhere will always be able to track what I'm looking at if they really want to).
