Google keeps on slimming down its product line to focus on what CEO Larry Page calls its “big bets.” Today it offered updates on five products that will be going dark this year. The photo editor Picnik, which Google acquired in 2010, will be closed down, and the team will work on Google’s other photo products. Google is also shutting down its Social Graph API as its Google+ API slowly trickles out.

Google will also open-source its Sky Map this year in collaboration with Carnegie Mellon university. The Google Message Continuity service, which backs up email for enterprise customers, will be retired in favor of Google Apps. The Needlebase data management platform will be integrated into other services. Finally, Urchin, whose product ultimately became Google Analytics, still had a standalone client-hosted version, which will be closed in March.
