Earlier on this week it was announced that some Google services will be closed.
These services have been considered redundant, not too popular, or not directly related to Google’s core business.
Here is a quick list:
3. Jaiku: Jaiku is a microblogging platform, which is going to be migrated to Google App Engine, and then released as Open Source. However the active development will be stopped. The service will continue thanks to some passionate Googlers.
4. Google Catalogs: Discontinued. To be honest I have never used that service before.
5. Dodgeball: A mobile social network which was acquired by Google in 2005, will be closed.
