This was weird: I did a Google search for something. I went off for a moment to a different browser window to read some e-mail. The e-mail happened to be a mail about the way that Google weighs link popularity higher than relevance in ordering the hits found. The other browser window happened to crash, and took all my other windows with it. When I brought the Google search back up, I entered the exact same search criteria -- and got different results! Creeeppppy!
