2009 Jan 27, 10:41I just noticed that Google's Feeling Lucky doesn't work if your query contains a 'site:...' entry unless the HTTP request has a referer header pointing to Google. This person noticed too and wrote a
Google App that acts like Feeling Lucky without this restriction. "It appears that Google has some secret threshold to decide when to get in the way of your destination like an angry ceiling cat
catapulting itself onto your face."
