39 Ways to Put Yourself on the Web
Tools for Building a More Perfect Web
You don't have to take the Web as it is. These two sites help you do your own in-browser customizations.
YouTube Remixer: This browser-based applet allows you to quickly add captions, graphics, borders, and transitions to clips you've already uploaded to your YouTube account. To get started, sign in to YouTube, and click Try Remixer. In the My Videos window to the right, you'll see thumbnails of your clips. Drag them into the editing window, and use the drag-and-drop tools to add effects. When you're finished, click Publish. Your original videos remain unchanged, but the edited versions appear on YouTube.
