It wasn't until this year that I started using Wikipedia. I've found it to be an absolutely amazing source of answers to absolutely anything at all. I was watching a John Wayne war movie, popped open the laptop and looked up Naval rank insignia. The other day for some reason I found myself looking up heat-engines and learning about the Stirling engine.
Today I'm reading political articles and saw this picture of The One. Not being young, hip, or cool I found his hand gesture peculiar. Luckily Wiki has the answers.
Of course, if I were Italian I'd be offended.
