It seems odd to me that you're arguing against these features, or at least against their necessity. Do you just not care, or do you actively think they're unnecessary? Have you actually tried to use Wave for the kinds of activities Google claims it's useful for? Because I have. And it's not. IMHO.

I wasn't intending to argue against an exporting feature. Wave has always seemed to be marketed as a solution for the inherent problems of separate hard-copies of documents, so to me taking a wave and turning it back into a piece of paper or a static document seemed to defeat the purpose of putting it on Wave in the first place.
I have not used it on a collaborate project, and I don't have to submit reports to a CEO (or anyone) for approval for what I do, so there were many things which I didn't consider. With your help, I now understand that there are cases where a hard-copy would be extremely useful, though I think part of the problem may be trying to adapt new technology to old ways, instead of creating new ways to use new technology. After all, there may be a solution that neither of us have imagined yet that doesn't involve exporting or printing.
When you present a project for approval to your CEO, do you show him all your notes and recordings of brainstorms and things like that? Of course not, hence the desire to eliminate the extra chatter, etc. And you don't expect your chalkboard or your (paper) notebook to export only the relevant information to a PowerPoint. So what do you do in a real-world environment when you're ready to turn the brainstorming notes and ideas into a presentation to get your project approved? My guess (since I haven't needed to do this, myself) is that you prepare a separate document for him which highlights the relevant information he needs to know to make a wise decision on whether or not to approve the project.
It might not be that difficult to have a brainstorming wave and then an official presentation wave. Or as the case may require, a brainstorming wave and then an official presentation document, such as PDF or PowerPoint. That's not so different from a real-life situation, is it?
Again, I'm not saying that I'm against the option to print or export. I just think since Wave is so new (and early in development) that we may not have fully considered what it was designed to do and how to properly use it.
I know I haven't.
