Meeting Topic for Feb 18th

I'd like for us to share experiences that each of us may have had recently with some of the many online tools that relate to our work. I'm thinking, for instance of the following:
(but not limited to)

• Github social coding
• Dropbox
• Rescuetime
• Keyword Generator by seobook.com
• Color Scheme Desginer
• Kuler
• Bespin
• Adobe BrowserLab
• ColoRotate

These are only suggestions or examples. Be prepared to talk/demo on one or more of your favorite online tools.
