Nick Carr’s been brooding about Google’s long-term product strategy. Here’s what he predicts:

Google Search (“Google” goes back to meaning just search: for all information types, on all devices, personalized)

AdMarket (a unified market place for buyers and sellers, spanning web text, web video, web banners, print, radio, TV)

YouTube (YouTube expands from video to become the common interface for all media sharing)

YouTools (what Apps for Your Domain morphs into, with different tool sets for businesses, families, universities, and hospitals)

YouFile (a personal information management service, covering health data, finances, etc.)
