the dog turd could cause the PM to slip, depending on how he fell it could have serious implications.
Personally I'm more worried about companies with monopolies over all else (primary Google, Microsoft, Apple, Amazon, etc.), because they just funnel everybodies info to only a selection of databases (since most of them make the bulk of their profit from selling advertisements based of profiling you). The whole government spying on it's on people and other people (afaik the US program of collecting information on foreign citizens in this style seems to be breaking most of it's allies national espionage laws), disturbs be mostly because of the countries claiming the greatest "democratic" and "liberal" governments in the world then collect all the information they can on you that if they were collected in similar ways on physical equivalents, would be unlawfully, and probably have a lot of government workers laid off, sacked and persecuted because they are invading peoples privacy - remember the phone hacking scandals?
eh but it's all a matter of paranoia built into governments after 9/11, should be interesting when a virtual police state is built.
Anyway, on those search engines, Startpage is one that uses google solely, while ixquick uses ones such as yahoo & gig , but i find that ixquick is more reliable to search with in terms of working (but so far I've only been using them under terribly slow connection, a government proxy & firewall, or both

) with both basically yielding equivalently useful results, i find. The free proxy's pretty nice too, as are the non cookie custom search URLs. Just best to read over the entire privacy page & privacy policies of both.
