Yes, I agree. I haven't done much good for the D community,
although I believe some of the code I've written for mysql native
is in production.
Let me add a point for Rust somewhat related :)
Community
---------
The community is nice, helpful and doesn't condecent people.

When "everything" is an expressions, you can write things like
auto a = if(e) c else d;
In D you have to write
type a = invalid_value;
if(e) a = c;
else a = d;
assert(a != invalid_value);

There are probably nothing in newer times that can be credited as
much pain as the incompatible runtimes of phobos and tango, but
I've still encountered a lot of compiler and phobos bugs. Yes,
it's just every 500 or so lines now, but I've only encountered
a couple of bugs in the C# compiler and a couple more in the .Net
library in several years - again credited to a lot more manpower
available.

I'm pretty sure Walter Bright has said this on a lot of occations.
He seemed to believe a failure of adoption of D was due to the
constant breaking changes, which might be true.

I didn't know that. Very nice. I hope it's in a clean state when
it gets pulled in.

Yes, but the hype is probably driving even more developers to the
language, and I believe a large user-base is of paramount
importance for a language to become good.

I disagree. String mixins are much easier to abuse than hygenic
macros. String mixins allows anything, and while it offers
infinite possibilities, it also encourage abuse.
