I believe Ixquick blends results from several search engines, like an aggregator. Startpage is by the same people but only includes Google results. It also has some Google-specific features like date search. The difference is pretty small though.
I'm not sure that's true, but in any case, being tracked is the price you pay for using Google.
The way I see it, there are three options:
* Accept it and keep using Google
* Use DuckDuckGo, Bing or some other search engine
* Struggle to use hacks like Scroogle
Tracking users is a key part of Google's business model. If you use their services, they're going to track you and target ads to you. And they're going to keep implementing things like throttling to frustrate sites like Scroogle.
personally, i just stopped using their other services (i tried disconnect, but vaguely remember various issues when otherwise logged in) - as far as i know, they don't track you when you're not logged in (to be more sure i also use ghostery - that, together with disconnect, prevents a lot of tracking).
yes, i know (and also browser fingerprinting if they really wanted to), but do they do that? as far as i know, they do not (likely for various reasons - bad press, confusion of people behind NATs, etc).
[i mean, more exactly, that i have heard nothing about them updating personal information with data from searches when not logged in; i am not talking aggregate info like typical searches from geoip locations]
It's not like they had a bunch of people sitting around a conference table thinking up the phrases people might ask it. It's a natural language parsing engine; it understands "horny" as sex, and pulled up related Yelp listings.
If a consumer does research, as I did, and looks for comparison of the eInk of the Nook and of the Kindle, you quickly discover side by side photos of the Nook and Kindle and conclude that the Kindle eInk is better (it does use a more current version of eInk than the Nook after all). If you wanted color - you with w/ the Nook because that was the option you had out of the big two, otherwise, with the Kindle.
