I don't think this is true for most people. This has been discussed on HN a few times. While the techie crowd usually has distinct sites for different purposes, this isn't true for most people. Facebook is the only thing a large number of people get on the internet for. Portals work at engaging visitors, it's just a matter of monetizing the eyeballs. Facebook has the engagement locked down, now they just need to monetize the eyeballs.

FB may have Bing search integrated, but its not in any prominent location. I've been on facebook for years and have never seen it, not once. Perhaps its integrated with facebook's people search? The point is, if they put a plain-ol internet search box on each users homepage it will get plenty of use. With the plenthora of data they're generating, internet search can be trojan horsed by way of a history/activity search.
