Though almost everything Google touches seems to turn to gold, there is one project that never quite became ubiquitous (at least here in the U.S.). Orkut may have found a following in Brazil and Asia, but I don't know anyone who uses the service. As Erick Schonfeld reports in TechCrunch, that may be about to change.
Known internally as Maka-Maka, the project will provide a means for all of Google's existing applications to work together within a social-networking landscape. Google is also building a series of APIs that will allow developers to integrate their own applications into the Google universe.
