It's good for recording normal applications. Though, it doesn't see tooltips and some max little windows, like when I weld in the video. But it can't record SC2 in fullscreen, and also, when I record sc2 it in window mode, the sound has a tendency to desynchronize. Maybe it's fixed in later version.
As my experience says, there are 2 kinds of noobs: the ones who use search and the ones who doesn't. And it feels like none of these will benefit from putting tutorials in one place. But as DrSuperEvil suggested, tutorials could be linked from that new wiki tutorials section.
