I get the impression that D has languished because it never placed itself as a language good for application development. In contrast, look where Pascal/Object Pascal (Delphi) went. When Pascal/Object Pascal got nudged out by C/C++ in system and embedded development, despite being and still is a strong alternative, it made itself useful in application development. IDE (Delphi & Lazarus), GUI framework (VCL and LCL), multi-OS apps, etc... It found a place to flourish, and is still being championed by various companies and taught in various school systems. Where with D, it seems to just be sitting in a corner, waiting to be noticed as a C++ replacement. But, people are not checking for D and hearing little about it. There is a long list of interesting languages, but if people don't see an almost immediate ROI for learning them, they will just sit and collect dust. Even if a language gets a bit of publicity, it still takes luck, timing, or corporate interest to move up the ranks.
