I was really into D, but I gave up on it because it seemed kind of dead. It's often not mentioned in long lists of languages (i.e. I think Stack Overflow's report did not mention it), and I think I remember once looking at a list of projects that used D and most of them were dead. I think I also remember once seeing a list of companies that used D, and when I looked up one of them I found out it didn't exist anymore 😐️
