I just checked that thread and he said it was on a guitar he assembled, and also that he resolved the problem. I'd not recommend saying something bad (or anything for that matter) about a forum member without contacting them first. That wont go over real well around here.
If you could take some pictures of the frets and give us exact action measurements (at the first, 12th, and last fret) and a little bit more detail as to the exact problem, (ie is it buzzing only when open, only on a certain fret/area or all across the neck?) we could better assess your problem.
