There's a new kind of personalized, social search available that may trump any effort we've seen from Google to date in this corner of search. Greplin is a new site that searches through "all your online data in one place, really fast" - or at least your the online data you have in the services that it supports, which is likely far from all of your online data. Still, the concept behind the site is pretty noteworthy, and it will likely add more services as time goes on.
