If your launcher doesn't support a widget or shortcut to an action, download Nova Launcher.
Keep Buzz as your home screen launcher and ignore Nova for this. Nova includes a widget linked to an action, which you bind to Sense.
Go into Sense, via your new widget, and delete all of the home screens except Blinkfeed. Hit the home button to go back to Buzz.
