Where is .NET?

Today at Digg/programming, not one single topic involved .NET. There were a lot of PHP, Ruby and Java. So where is .NET? Why is .NET so under represented on the broader community sites? I don’t think it is because PHP or Java has a bigger user base or is better or worse than .NET. It must be something else. Maybe it is because .NET developers just don’t care about the other programming languages and platforms. That’s fair enough, but I don’t buy it.
