For the past few versions now I haven't been sure where to check my buzz stat. Is it still part of the game? If so, where do I look to check it?

Hi dabow! According to the devs, the buzz feature is being gradually removed from the game. Based on changes that have been implemented in the last few months, they figured that buzz wasn't really that impactful anymore, so don't worry about not being able to see your buzz meter :)
