My two cents on what D needs to be more successful...

Don't worry I'm on that too.

Simply at the moment, I'm currently writing a D tutorial for 
total beginners, based on the materials I made to teach 
programming to my children.

As the theory and exercises are currently in French, I'll have 
translate them, which will take some time.

And now I'm also maintaining several open source tools.

As for everybody my free time is limited, but I'll do my best to 
test the future std libs, and help debug them.
