> mainstream .NET and C# community didn't really "get" Open Source
I don't think it's that they don't "get" it....for those who are aware of its existence, I'd suspect it's moreso that they just don't "do" it (for whatever reason), and for others it's simply that they don't care. You can not care about it and you can go on to have a successful career and be an accomplished programmer. The same programmer would be even better if they did embrace the open source community, but not everyone aspires to be in the top x% of programmers.
