I changed the Scroogle search on
Wikipedia-Watch so that it uses the SSL (secure socket layer) option. That's the little padlock image you see on your browser when you enter a site that asks for personal information such as credit card numbers.
The reason I changed it to SSL is that in cases where you are searching for information on en.wikipedia.org itself, or particularly when you are sleuthing around some some editor's own site or blog, you don't want him to know that you initially arrived there from Scroogle. The SSL in all browsers blanks out the referrer when it takes you to any of the links that you click on from a secure page. By going to those sites with a blank referrer, you will look like any of the thousands of bots that wander around the web all day long with blank referrers.
Now you may think that just using Google directly is okay, because everyone uses Google and you'll get lost in the crowd. But that's not true. Google and other search engines not only show where you came from, but the website owner with access to referrer logs can also see exactly which search terms you used to get to his site! That is definitely not recommended for web sleuthing. It can set off alarm bells when the website owner sees this, and he might make a note of your IP address.
