Except that both of those tools are the absolute worst at their respective jobs!
Standard duct tape uses an awful adhesive that depending on the humidity turn into a gummy mess or desiccates into flakes -- either way leaving a difficult residue and not actually holding. The loose right-angle weave of the coarse fibers means that it has zero shear strength on the most common axes, and is prone to splitting when under tension. The outer vinyl layer will separate on its own in heat, leaving a mess of fibers + adhesive behind.
WD-40 combines a solvent, a mild lubricant, and an adhesive (!) -- it's extremely prone to collecting grit and caking it onto surfaces. It will displace any better lubricant it is applied onto.

I hear what your saying but I'm talking hacks (http://www.flickr.com/photos/bootload/3961148668/) not engineering ~ http://www.flickr.com/photos/bootload/3960385835/
I think you make a very good point on taking Spolsky seriously.
