I just have a "Recipes" folder on my laptop, and sub-folders by topic heading. All of my recipes are printed out and are in a binder with protective sheets to keep them clean and dry. It's my KISS method of recipe organization. Oh, and it's all backed up on and external 300GB drive...just in case!
Recipezaar is also a really interesting idea, as long as they don't shut down the site. Nothing is forever. I only trust my recipes to my computer, and it also makes it easy to send a recipe to someone in a Word document or cut-and-paste into a forum topic.
