Now I've seen everything
When I joined Netflix in January of 2004, I was so excited, that I quickly filled up my queue to the limit of 500 titles.* Since then, I have been tracking my Netflix history using a program called Netflix Freak, and as of today, I have watched 500 DVDs from Netflix. If I hadn't added any new titles in the last years, I would have emptied my queue today.**
*because of the Profiles feature, you are no longer limited to 500 total, just 500 per profile. If you want a longer queue, add a profile.
**My queue has 100 items in it today, not counting the saved section.
