The "Ask" toolbar is bundled with a lot of crapware. Could explain the inflated numbers. I doubt any Ask users don't know of Google - more like they don't know how to switch, or don't need/want to.
I'm always suprised when I open a browser of some collegues/friends with even moderate computer literacy and see the amount of crap they let automatic installers shovel into their PCs, and how they are mostly not bothered by it.
I really don't understand why Oracle, a company that rakes in almost $40 billion a year, is begging for pocket change from Ask Jeeves. Someone please explain this to me.
