What is spam? A funny way to look at it would be this: Spam is something (usually ads) that shows up where you normally would expect to see your information, messages from your friends. Annoying? Sure! Which is (to me) is not that much different from how ad-supported companies like google and most Web 2.0 startups work: they show you ads instead of useful content. Of course it is instead, because we consume information from our monitor screens, and each pixel of monitor real estate, occupied by ads, is a pixel stolen from you. Same applies to bandwith as well. Ever since I installed ad-blocker extention to Firefox, I've been enjoying a very noticeable speedup in page loading times. Therefore, google building sophisticated spam filters is essentially a war between spam generations: spam 2.0 vs old spam :-)
