That's true, John but there is almost infinite corporate demand for ASP.NET.
That paradox will resolve itself one day I'm sure and I suspect the winner won't be ASP.NET unless things change.

I did a web site for a small company with ASP.NET.
When I tried to run it on GoDaddy the performance was abominable.
The GoDaddy tech was cooperative but honest and he advised me to redo the site so that it would run on Linux because ASP.NET used limited shared resources while the Linux service was virtually unlimited.
I did it over in vanilla HTML/CSS with Dreamweaver - it took longer to develop.. but the site ran ... like a Fox!
Large clients don't have those kind of issues - yet- but sooner or later inefficiency will surface itself and become a target.
I see things like SignalR and I wonder whether MS is taking that issue on.
