Demo Girl demonstrates new online tools and tips and tricks via screencasts rather than in an article. Demo Girl is Molly McDonald and she provides brief tours of new websites and tutorials that are designed to replace faqs of these items. By watching a demo you will learn enough about the product or tool to determine if is something you want to use.
Recent demos have included a tour of Ubiquity, 3 Firefox Extensions That Make Tabbed Browsing Better, and Make Your PC a Little Greener with Edison.
If your preferred method of learning is watching rather than reading this is definitely a feed to add to you reader.
