The site www.freerepublic.com is running Apache on Linux.

I wouldn't exactly boast about FR running on open source tools. The responsiveness is pretty bad, it's had all kind of index corruption problems, and it falls over under any kind of serious load.

Yep. My company, a major bank, is rapidly switching all of our Java based sites to ASP.NET. In fact, we already set an end-of-life date for all of our Sun boxes. We evaluated Apache/Linux and found the administrative costs were higher than on the Wintel platform. We've found that hardware/software costs are lower with .NET, and our programmer productivity has increased significantly.
