Uh, really? In my experience, at least a quarter of the info it gives me is usually manufactured or incorrect in some critical way.

In fact, if you switch to "Pro" mode, it frequently says the complete opposite of what it claimed in "Fast" mode while still being ~10-20% wrong. (Not to say it's not useful — there's no better way to aggregate and synthesize obscure information — but it should definitely not be relied on a source of anything other than links for detailed followup.)
