I really hate Google Instant and autocomplete – largely because I hate any user interface element that causes things on screen to change in unexpected ways. I also hate websites where little ‘preview’ windows instantly pop up when your cursor crosses over a link. When something unexpected pops up on my computer, I always think: “Waah! Something unexpected and unwelcome has surprised me unpleasantly!” and never: “How delightful! My computer did just what I wanted, without me even asking!”.
I am rather annoyed that even when you turn off Google Instant, Google turns it back on for your account after a few weeks. They really want those extra advertising revenues.
It is possible to avoid both annoying features by searching Google using this link. I call it ‘Quiet Google’ and it helps conserve a measure of calm in the universe.
