Google's unified profiles are slowly added to all Google services that allow user-generated content. "A Google Profile is simply how you represent yourself on Google products — it lets you tell others a bit more about who you are and what you're all about. You control what goes into your Google Profile, sharing as much (or as little) as you'd like," explains Google. For now, the profiles are displayed next to the list of shared items from Google Reader, in the Google Books library and next to the custom maps, reviews and edits from Google Maps.
