I would be too; it worth noting that doing separate things in overlapping-but-not-identical domains and then merging them over time (especially when one is an acquisition, like QO) isn't really unusual for Google (and increasing the overlap on the way to merger isn't unusual, either.)

QO's been around for quite a long time, and is a fairly recent acquisition. Its not a new offering, the news here is that its just been made free.
