Irony(?): it's priced high relative to "professional" pure-play drawing apps like SketchPad and Brushes, but by omitting needless features like color and brush controls and adding the one feature of collaborative diagramming, it's probably going to be more valuable to me than either of those other apps, which I mostly use to goof around with my daughter.

Finding a high priced product more valuable is not ironic :)

I'm pretty sure I'm not finding the concept valuable because of the price point.

I think it's debatable whether colors and brush controls in a sketching app are "needless" even though they may be needless for 37signals very narrow internal use case.
