According to spam filtering company MX Logic, spam as a percentage of all Internet email went down in October. This was the first noticeable decline since tracking started. Before you get excited, let me tell you it still accounted for 89.8 percent of all email traffic. Imagine that! If the noise ratio in anything else we do was that bad, we'd probably stop doing it. However, my Indianapolis computer consulting customers list email as the first or second most important service provided by their computer system. Many would rather be without phones than without email.
