They also are supported around the whole edge of a two-foot-square
square. If those shelves were supported every two feet - especially if
they used that kind of thickness - I bet they'd still be just fine.

>From an engineering perspective, I'd say that particleboard is fine for
carrying loads in the right circumstances, but it is incumbent upon the
designer to know what those circumstances are and design accordingly.
Building codes (which were cited in support of the notion) tend to be
conservative, and (especially given the likely blind substitution of
particleboard for plywood) I'm not surprised they take the tack
