I’ve done a fair bit of hand-wringing about wireframes myself (see here and here), so I read Travis LaFleur’s Toward a More Expansive View of Wireframes with great interest. I really like Travis’s approach of expanding wireframes beyond their traditional use:

Rather than thinking of the wireframe as a low-fidelity, grayscale snapshot of what a page will eventually look like, coming further and further into focus as the design is refined, we can embrace a broader view of the wireframe as a thematically rich conceptual model — one that is now depicting page-level details, reinforcing previous models of the system as a whole.
