When I run out of things to watch I spend a lot of time scrolling through the Netflix home page... I did finally use a category code and it was brilliant. I found a few shows to watch that I hadn't seen before. The video's kind of long but there are actually some pretty good tips in here.
1) Categories
2) 5 Profiles - great if you had kids or want to separate your favorite genres.
3) Discounted gift cards. Use a gift card to buy a gift card? What?!
4) whatsonnetflix.com
5) Google Chrome extension that gives you show ratings plus trailers.
