I wouldn't say it's as bad as 9/10. They don't mostly use Y! results from what I've heard from Gabriel. They do their own crawling and ranking too, so I do expect results to improve. They can afford to be more liberal about banning spammy sites, which helps a lot.
0-click info and search ideas are really nice features. Another useful hashbang I use a lot is !a which searches amazon directly.

It's cool, but I've not seen it helping much so far, since the base results suck ridding them of some of the crap don't improve them noticeably.

They're nice features when they display information I want. They generally don't.

No. Just no. Firefox has been able to do that since 0.9 if not earlier, I'm sure other web browsers can handle that as well. I have no need whatsoever for the indirection through DDG. Here's how I search amazon: focus address bar, type "a somethingsomething", return.
