Really, why did anyone ever switch from Yahoo? It wasn't for the results, Google provided the search results for Yahoo for awhile. Many people, myself included, switched to Google for the clean interface.
Now I've switched to DDG not just for the results (which are 95% "just as good") but for the privacy, the variety (I like the idea of competing services), and some of the interesting things DDG is doing with providing information directly.
As I've said before, search is an intensely personal tool. Don't use a tool if you don't like it, but recognize that other people might like a tool even if you think it's terrible.
The ONLY thing DuckDuckGo can do that Google won't is "privacy" (maybe "less ads" is another thing). While that might be reason enough for some people to switch, it's barely going to make a dent in Google's dominance.
In the AOL case, while IP addresses were stripped, users were identified with unique keys so you could see individual users' search sequences. That is not the case here.
Use the tools that make you most productive. For me, that's DDG. For you, maybe not. But I think "...there is no reason to switch to them" just isn't accurate in general.
By quickly, do you mean in less time (search speed is more), or in fewer clicks (search quality is more / relevant links are above)?
I suspect we all tend to search for the same types of things over and over. Ruby developers search for Ruby docs and modules, stamp collectors search for auctions and information about stamps, etc.
So I fully understand that my experience won't be shared by everyone.
I finally admitted to myself that I was wasting too much time having to run so many searches twice and I switched back to Google.
I'm not particularly disapointed with google search, and if I try something I don't like, I won't try it again unless a friend tells me it's changed a lot.
That business is clearly one-shot, either v1 is good or you're going to have to fight uphill against a bad rep of your own making.
[1] indicates DDG uses third-party APIs for deep web searches. To me that sounds like how Inktomi was a "search engine API" and neither Inktomi nor Yahoo saw Google coming [2].
Even if DDG doesn't succeed, Google is now at the top of the hill and therefore is _the_ target for all competitors.

Ads can be a major pain, and any business that requires them is probably going to fail, intolerance to ads is building up as ads are more and more agressive.
Switching to DDG because of ads wouldn't make much sense, they'll get their own ads when they have to pay for servers, too.
Anyway, my point is that 1% of the search market is about half a billion dollars in revenue.
It'll be interesting to see if Gabriel keeps up with the affiliate model or moves toward an in-house ad solution.
Bing is 20% of search market yet last I checked they are nowhere near that amount in revenue
How so?
DDG offers privacy, something that Google and other big search engines do not. That is more than enough reason- especially with growing privacy concerns in the US.
