Just some additions, for the other seventeen check out the Favourite Things page.
18. Rainy Mood. Question: ever thought to yourself "What I'm doing/not doing is great, but wouldn't it be better if it sounded like it was raining outside?" Well, my old roommate did, and that's how she found Rainy Mood. I think it started out as one of those things that's supposed to help you fall asleep at night, but honestly I like to play it with jazz and big band music because for some reason it makes life seem better. If you're a freak like me, take a look.
19. Cracked. Cracked is a great website for those of us who love random movie trivia. They inject all of their work with a sense of humour so longer articles keep you interested. A good one for all the film buffs out there.
20. Internet Movie Database. Ever been watching a movie and said to yourself "Where do I remember that guy from???" Well, IMDB is here to solve all your problems. You can search actors, films, directors, etc and see filmographies, upcoming projects and related articles as well as bio information, photos and trailers. Very useful for solving film-related arguments.
21. Vogue's website. I won't pretend I bother reading much, but I do find it indispensable in that they dependably provide images of all clothing from all the runway shows, broken down according to season and couture, ready-to-wear, etc.
