I'm not sure how you got this from that post, if anything the future has never looked brighter for .NET/C# developers. The ability to target all mainstream platforms, a burgeoning open source community, and fantastic tools. Of course, other technologies have had these in one way or another ... but that doesn't invalidate the C# communities advancements.

The fact is that as a C# developer currently focusing on mobile development, I am very happy these days.
