Google has just announced on their blog that they will be shutting down Google Buzz in a few weeks. Users will be able to take out their data from Buzz with Google Takeout, but it will still be viewable on their Google Profile.

In a few weeks we’ll shut down Google Buzz and the Buzz API, and focus instead on Google+. While people obviously won’t be able to create new posts after that, they will be able to view their existing content on their Google Profile, and download it using Google Takeout.

Google also announced a slew of other products that will be closed in January of 2012, including Code Search, Jaiku, and iGoogle’s social features.

So what’s up with all of these product closures? As explained before, and also in yesterday’s earnings call, Google is trying to put more focus around core products. In today’s case it looks like these products will allow the Google team to focus more on Google+. I think we’re all fine with that, right?
