actually you do not have pay for it (unless I got it free for getting Stat Tracker). They will show the top five people that are added/dropped for the last twenty four hours. IF you pay for it, you get to see everyone. I just like to check it everyday because it can alert you to some people to research. Just click on the "Research and Analysis" tab and it should show who is Hot and the Buzz Index.
Ps 12000 people have now added Lidge and another five people dropped him. If you dropped him this afternoon, you are the worst fantasy owner of all time.
