With Facebook changing its privacy policy and settings so frequently and just generally the huge amount of social sites out there, for many of us it is far too late to ensure our name doesn't show up with unfortunate results in web searches. Information is too easily copyable and archive-able to make removing these results a viable option, so clearly the solution is to create more data.

Create fake profiles on Facebook using your name but with a different photo, different date of birth, and different hometown. Create enough doppelgangers to add noise to the search results for your name. And have them share embarrassing stories on their blogs. The goal is to ensure that the din of your alternates drowns out anything embarrassing showing up for you.

Although it will look suspicious if you're the only name on Google with such chaff. So clearly you must also do this for your friends and family. Really you'll be doing them a favor.

One of the more limiting issues of writing client side script in the browser is the same origin limitations of XMLHttpRequest. The latest version of all browsers support a subset of CORS to allow servers to opt-in particular resources for cross-domain access. Since IE8 there's XDomainRequest and in all other browsers (including IE10) there's XHR L2's cross-origin request features. But the vast majority of resources out on the web do not opt-in using CORS headers and so client side only web apps like a podcast player or a feed reader aren't doable.

One hack-y way around this I've found is to use YQL as a CORS proxy. YQL applies the CORS header to all its responses and among its features it allows a caller to request an arbitrary XML, HTML, or JSON resource. So my network helper script first attempts to access a URI directly using XDomainRequest if that exists and XMLHttpRequest otherwise. If that fails it then tries to use XDR or XHR to access the URI via YQL. I wrap my URIs in the following manner, where type is either "html", "xml", or "json":

        yqlRequest = function(uri, method, type, onComplete, onError) {
            var yqlUri = "http://query.yahooapis.com/v1/public/yql?q=" + 
                encodeURIComponent("SELECT * FROM " + type + ' where url="' + encodeURIComponent(uri) + '"');

            if (type == "html") {
                yqlUri += encodeURIComponent(" and xpath='/*'");
            }
            else if (type == "json") {
                yqlUri += "&callback=&format=json";
            }
            ...

This also means I can get JSON data itself without having to go through JSONP.
