What I find bizarre is why he's singling out Visual Studio. Just about every game for every platform has achievements nowadays. Even Minecraft has achievements! None of these are tied to Xbox Live.

So why single out Visual Studio achievements, which aren't even part of the core VS product (it's an add-on), while there are tons of AAA games stepping on his turf too?

Also, achievements or gamer score literally means nothing. It's e-peen, pure and simple.
