D is not ready for anything. At the very best, It's in alpha. Don't let others make you think otherwise.
DMD is one of the buggiest compilers out there. If you are a non-DMD/Phobos developer and think that D is ready for any kind of work then you must be high on dope. If you want to learn a new programming language and experience D, then go for it. The language itself is very enjoyable, specially if you are coming from C/C++/Java. However, anything more than a 1K LOC is going to get you in trouble, specially if you decide to use one of the _nice_ features of the language. Yes, things are improving rapidly, but I would say it's going take at least another year before DMD is stable.
