What's another way we can organize your computers? What about email? Your Favorite Websites? Your Blog Posts? RSS Feeds? Reply to this post with specific ways, websites that can help you, and anything else you would want to add.

I can organize my computer by creating folders and storing all of my documents into their corresponding folders. I can organize my email by adding tags to the email and creating circles between the people who email me. I can also organize my blog posts and my RSS feeds by date and have the older posts be last on my list.
