GOOGLE -- I cleared my Google Search History and trust that Google is correct: "Your search history is currently empty." But in the back of my mind, I know it isn't. I get paid by Amazon because I allow A9 to cache my search history. Alexa lets me influence page ranks because I permit a set of "severe" entries to my computer registry. I know that anyone with a talent for computer forensics can open my local hard drive, then scroll through my internet hard drive, follow the pointers to my internet cache and learn more about who I am by reviewing where I've been. Headhunters do this now. Some finance companies and stateside social welfare agencies excel at the practise of locating people through pointers they find electronically. I think the days of volatile browsing history are well and truly an item of the 20th century. Search histories, like cookies, have developed a persistent nature. Once you're on the internet, you're often archived forever. This realisation is part of the reason that some astute writers of Irishblogs refuse to be photographed or tied to their surnames. With good reason, because people write about personal views not meant for widespread consumption.
At the time of this writing it is important to note that if you intend to use Google Search History, be aware that your Google search history main page contains your last search in the URL because it's a “prev” parameter. Sites you then click on may thus check their referrer logs to get to know what you were searching for previously. If you intersperse you searches for video cameras with searches for sex sites with webcams, you may be revealing more about your private life than you intend. Google should fix this "prev" parameter issue.
