My company actually does use its own software internally. One of its offerings is a web-based e-mail and calendar system, and all employees are "strongly encouraged" to use the application and report on any bugs. It's not as good as Microsoft Outlook (yet), but I can say that by having so many employees use the application, is has definitely increased the quality of the product. For my company at least, "dog fooding" the product has been a smart move.

By the way.... I like the new site. Keep up the good work. 🙂
