All those who use google buzz theres a sad news. I just saw the notification pop in my gmail account that google buzz is going away and pls backup your data.
From Official google blog
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 buzz was one of the biggest flops and its apis are now going to be integrated with Google+. I dont think Buzz would be missed a lot due to the fact that G+ has taken over. Anyway RIP GOOGLE BUZZ!!.
