Imho, D's choice to be garbage collected has prevented wider adoption (that's the case for my usage at least). And as a compiled gc language, it competes squarely with golang, something that's likely hard to do, given the corporate (google) support golang has.
Side note: I met the creater of D, Walter Bright (also of course famous for the digital mars compiler) at going native 2013 (now known as cppcon). Bright was the nicest guy, and was happy to field my questions. We even chatted about rust, which was just a twinkle at the time!
