Definitely worth looking into:
The Web Fire Escape is a simple device which has been designed to allow readers of weblogs to instantly replace a Web Fire Escape equipped blog with an alternate work-safe site or a fake word processor or spreadsheet application. When you see a weblog with the Web Fire Escape equipped button
you can be sure that career salvation is only a click away should a work colleague or manager approach your desk whilst you are catching up with your daily blogs.
