GoogleFight

Today I was introduced to a Google goodie (not affiliated to Google) I wasn't aware of - GoogleFight. It's a simple site that lets you compare the number of results Google returns for two different queries. So you can easily compare the popularity of things (or people) - apparently, despite SVM's superiority in most cases, Neural Networks are much more popular than Support Vector Machines. "Madonna" is 4 times more popular than "Britney Spears". There is much more "good" than "bad" in the world. You get the idea...
Alternatively, you can check expressions and improve your writing - the American way of writing "color" is so much more popular than the English "colour". It's better to "speak english" than to "talk english", etc.
Nice...
