Please don't get me wrong, I also love D, I've used it everywhere I can and I'd say it's my favourite language (yes I have one...) but I'm as as the reddit's OP, trying to understand why it's unpopular.

I don't think it is reasonable to say it is unpopular, [Github 
activity shows that people create new projects with 
it](https://forum.dlang.org/thread/ltfgzovqcadknyjnabwp@forum.dlang.org) at roughly the same rate as Nim, Crystal and other smaller languages.

What would be interesting to know is what made people who were 
very enthusiastic about D in the past (in the forums) switch to 
another language? Which language was it and why was that a better 
fit for them?
