"X of Y" is how Hollywood describes new scripts. The danger is that this is also how Hollywood comes up with new scripts. Have we gone whole hog and transformed into a fashion industry? Are we optimizing for quick wins, sequels of existing software, at the expense of real innovation?
However, you should note that you probably won't be creating / riding the Next Big Wave by crafting new things in terms of existing things.
And Google was the better-AltaVista of AltaVista. I'm just saying, those are pretty big waves.
So maybe it's more true that originality hurts. That is, you don't want to be as original as possible, you want to be only as original as you can afford to be.
Joe Kraus's stellar lecture at Startup School last year explained this pretty well.
Problem here is the X of Y description doesn't make obvious sense, at least to me.
