It's pretty obvious that these changes are from Micro$oft. Redesigning the feed, adding a pro tag, etc. They all seem geared toward emphasizing the social aspect of GitHub, for future integration with LinkedIn or what we don't yet know. I agree that no change isn't realistic, but GitHub has always been a place to code, not link your LinkedIn profile or socialize. I fear that if they go down this route, they'll go to far and GitHub will lose what made it special in exchange for becoming a "Jack of all trades and a master of none."
