As you can see at the bottom of the page, this site is powered by the BlogEngine.NET open-source blogging software but, yes, it is running on Linux with Mono and Apache.

There have been just two issues with case-insensitivity in BlogEngine.NET source code, but otherwise the deployment went without any issues what-so-ever! This is a live proof for both Mono and Mono's ASP.NET maturity as well as the .NET's realized promise, thanks to Mono again, of enabling one to write and deliver cross-platform software.
