StartPage is a mystery to me; they say they're "enhanced by Google", but what does Google get out of providing their search results to a competitor?

Also heard rumors about StartPage being very shady. Would be nice to get some confirmation on this or to learn that it was only a campaign by competitors. Google for "StartPage malware" ;)

put a little extra effort in

So it's hopeless then. You're never going to convince anything resembling a sizable portion of the population to put in more effort for no easily appreciable benefit.
