You make a good point that I won't find nearly as much in the way of ASP.NET and C# as I would on other platforms, but for now, those are indeed my flavors and will likely continue to be as most of the development jobs in my area are using Microsoft's solutions.

I appreciate the suggestion of Codeplex. I remember hearing and learning about that at a Tech Fest in Indy several years ago and had since forgotten about it, so I'll definitely be checking that out.
