Based on how many you've checked off, you're ranked among the other members of the site and you get "awards" based on how many films you've checked off certain lists.
If you're someone like me who loves lists and checking things off thereof, you should definitely check out the site! It's great fun and it's pretty nifty to have little goals in you film watching. For example, I'd like to finish the "AFI's 100 Years... 100 Passions" list soon (I'm over half way there! Yay!). And one of the best things is that many of the lists aren't static, so you will never have watched all of the films on all of the lists because new ones are constantly being added!
