The whiteboard is a metaphor

I think that I may be too exacting for my own good. Even so, I feel that it is necessary to mention that the "whiteboard" tag on this very blog is not entirely literal. It is in fact partially metaphorical. Things that are tagged with the word "whiteboard" may never have actually made it to my whiteboard-o'-clever-ideas. They may come straight from my sketchbook, or a scrap of paper, or some such thing. But they are things that belong on the whiteboard. That's why they get the tag.
