Google has long believed that thoughtful iteration is the best way to build useful products for our users. As part of that process, we are always looking for ways to better focus our teams on the products that can have the most impact.

As we mentioned last April, we are in the process of porting Jaiku over to Google App Engine. After the migration is complete, we will release the new open source Jaiku Engine project on Google Code under the Apache License. While Google will no longer actively develop the Jaiku codebase, the service itself will live on thanks to a dedicated and passionate volunteer team of Googlers.

With the open source Jaiku Engine project, organizations, groups and individuals will be able to roll-their-own microblogging services and deploy them on Google App Engine. The new Jaiku Engine will include support for OAuth, and we're excited about developers using this proven code as a starting point in creating a freely available and federated, open source microblogging platform.

Some of you may also be familiar with Dodgeball.com, a mobile social networking service that lets you share your location with friends via text message. We have decided to discontinue Dodgeball.com in the next couple of months, after which this service will no longer be available. We will communicate the exact time-frame shortly.

Finally, in the spirit of onward and upward, we have decided to shut down the Mashup Editor, currently in limited private beta, in favor of the more powerful App Engine infrastructure. Existing Mashup Editor applications will stop receiving traffic in six months, and we hope you will join our team in making the exciting transition to App Engine.
