He's not, AFAIK. AFAICS, Mr. Gaider is a storywriter, not a codewriter. (He or someone else can correct me if I'm wrong.)
He writes the characters, the dialogue, the story, the setting, the lore, and the novels (which enrich the lore), but doesn't actually do any of the coding, pixelmaking, or scripting.
Personally, I have no complaints in this area. I think the Architect character is fascinating (I don't trust him further than I can throw him, but that's a separate matter). I thought the new characters were well written. I really did enjoy the short, but sweet, story arc of the expansion.
The bugs are the problem of coders, the graphics problems the pixelmakers. If you want to attack Mr. Gaider for things he can't control, fine, but it is true, those are not his domain.
I am glad Mr. Gaider not only reads but participates in the forums - he should not be chastised for doing so. There are many developers who would never bother.
