> We all know...

HN isn't as homogeneous as you think. By this measuring stick, half of the posts on the front page can be put into question every day.

As evidenced by several other comments, even if someone already knows about D they can still use posts like this as a prompt for talking about their experiences and current thoughts about it (which can be different from 1, 5 or 10 years ago).

Weird post. How does one of today's 10,000 who have never heard of a subject learn about it?

Genuinely curious as I'm relatively new compared to the time of inception of this language. Can you cite the reasons why people didn't choose D?

even in this empty thread there are people who dont know it.

It's a programming language that some people like, and or would like to see become more mainstream?

I think any presumption about what "we all know" will earn you downvotes.
