Christina Wodtke on why she’s over wireframes:

I haven’t heard much lately about why wireframes are so awesome. I know they are incredibly useful as a thinking tool. I can’t work through an idea without getting out a pencil and scribbling out some wireframes on a pad of paper. I’m not sure they are good as a communicating tool.

The article itself has a reasonably articulated argument, but the discussion is probably more valuable.

Wireframes are just a tool, and all tools can be used inappropriately just as easily as they can be used well. I think it’s perfectly reasonable to say that in certain situations, wireframes aren’t particularly valuable, and Christina may exist in one of them. I think most folks, however, find themselves in scenarios where there remains a legitimate need for the wireframe, both as a thought aid and as a communication tool.
