Yolo Army seems pretty shady.
But I must take umbrage with Jim's claim at about 9:30 that he "was one of Greenlight's biggest boosters" but now it's "slowly become a breeding ground for lazy hacks". Just to clarify--this is exactly what you would want to have happen. All the stuff that's actually professional makes it on to Steam, either because increasingly developers simply bypass Greenlight, or because those who do go for Greenlight get Greenlit quickly.
It would make sense if the argument was "Now that no one takes Greenlight seriously anymore, the good games are lingering there"; but it's not. Jim then notes that he's started a series called "Greenlight Good Stuff" to highlight good stuff on Greenlight, and that it's already producing results; they got "Shots Fired" greenlit! Well, sure, that's technically true. Except "Shots Fired" was only on Greenlight for 10 days total. It certainly would have been greenlit within its first month regardless of calling attention to it. It's not like it was lingering in the depths of Greenlight for months, crowded out by the Yolo Army, and then brave Jim cut through the bullshit to discover it. By all means, call attention to good stuff, but there's not an actual problem here.
Assuming the process works, the vast majority of stuff on Greenlight on an ongoing basis will be bad.
