Web Filter

I've decided today that somebody needs to develop a web filter that automatically erases any references to certain topics when I surf the net.  For example:  what made this come to mind was one too many links popping up today regarding Wikileaks and Julian Assange.  I've heard enough about that and would like it to go away.  And go ahead and delete anything about Mark Zuckerberg while you're at it.  I don't want this filter to block any page that has these topics, simply delete these words from any page that I surf to.  All you web developers reading this, get cracking.  There's a cup of coffee in it for the first person with a working prototype.
