In my job as a systems administrator, spam is one of those things I accept as fact, but have to deal with as best I can so my users can actually get work done. I came across this article on Slashdot today, and even though there's absolutely nothing revelatory in this article, I think people fail to appreciate where spam comes from. It's not evil spammers sending you junk mail; spam comes from computers running Microsoft Windows that have been infected with something. If you don't like spam, stop sending Microsoft money for their software. Every time you buy a Microsoft product, you're supporting all the network effects of their software. The same network effects that make sharing a Word document with other Microsoft Office users easy, also result in more infections, more spam, more wasted time and money.
