Tens of thousands of non-programmers. A few minutes spent in the livestream chat feed was enough to drive a sane man to madness. 50% of comments were asking if the stream was minecraft 1.8, the other 50% were rude comments about Notch's marriage/weight/work ethic/etc.

Many of the people asking if it was Minecraft 1.8 were just doing it to bother others.

The MC 1.8 people were, but a LOT of people were also "what compiler is he using?" and other similar questions that showed the one asking had little to no knowledge of programming. I'd bet at LEAST 60% and probably more like 80 had minimal to no knowledge of how to write real code.

Including this guy right here. While I'm a programmer, I've never done any games programming, and most certainly have never done anything in 3D -- it was a learning experience for me to watch him. It was also inspiring, such that I may eventually enter an LD event myself.
