Selection Bias In Action

Saturday, for first post for National Blog Posting Month, I wrote a paragraph about installing a network printer on a Mac and a PC. I noticed a new (to me) feature here on to add a poll to a post. I like to play around with new features, so I added a one asking whether PCs or Macs were better (a poorly constructed poll, I admit). When I checked the poll, the next day, there were two votes: one for PC, one for Mac. Sunday a wrote a review of a an iPhone app that was linked by John Gruber over on, a very popular Apple-focused blog. Today, there are 42 votes: 40 for Mac, one for PC and one for Neither.
