is D worth learning?

The D programming language... is it worth taking my time off my current projects to learn?

I've actually found one independenet game programmer who uses D -- source code included with this halfpipe shooter called Torus Trooper is written entirely in D.

But will this language ever really take off enough to warrant learning it?  There aren't even any books on it, and that may be a bit of a handicap in really getting mentally "into" it.

Even if I'd like if it did, I don't think it won't get really popular. The author wanting to profit from his work (which is legitimate) is unfortunately incompatible with not being a big corporation full of enterprise business solutions to advertise it in magazines managers read, and the fact there's good, free, popular competition. So learn it as a hobby.

Better yet (unless you'd like a lower level language), learn Python or Ruby if you haven't, and perhaps Lisp (even though I hear learning Lisp feels like having a fetus shoved up your ass, and then having to shit it out while a big bad nigger is trying to shove it back up with his humongous cock. All while the fetus is growing at a steady pace.)
