No need to click the "search" button any more: Google unveiled "Google Instant" on Wednesday--a tweak to its search engine that streams in results as you type and tries to predict what you're searching for. Basically, you'll never have to leave the Google.com page. For now, the feature only works if you're signed in with a Google account. Gawker's Ryan Tate admires the product but says "it's got the potential to alienate some of the site's 1 billion users."
