Sometimes I wish I could downvote stories like this (and I use that term very loosely in this case) and have HN automatically ignore any votes by anyone who upvoted it from that point forward on every other post. That way I could filter out things people upvote without reading the actual post.
Sure it would scale terribly, but it would make me feel a lot better.
D has competing "standard" libraries, no major backers, and no "killer features". It may be a net gain over C++, but it lacks flash, marketing, and arguments compelling enough to overcome inertia, while having one major wart that turns people off (the library situation).
D is doomed, but not because there's something fundamentally wrong with it, but by circumstance.
