It's best for cold hard facts, so getting used to the types of search queries that work might take a bit. It's a little more picky about search terms.

Google is set to launch the Labs version of Google Squared later this month. Similar yet different, the release is likely timed to steal some of the thunder of WA, which was getting much hype as the latest Google-Killer (right). Guess that's the beauty of competition working for us, eh? Anyway, two new tools for the kit. Great for students and research uses as we don't have to weed through all the junk results Google can sometimes spit out.
