I have event sites with several thousand events, and we have programmed them to NOINDEX any taxonomy pages that don't have active upcoming events*, because blank pages are not a good user experience.
How do you think a user feels if he is searching for an answer to something and comes up with your blank page that lists a question with no answer? I see this a lot (increasingly on page 2-9, by the way), and it pisses me off no end when I do. If it happens enough, I avoid that site whenever I see it in the SERPs, because I can't trust it.
If you think it's an imposition to remove low quality pages, that's certainly your prerogative. But I would be willing to bet Google pays attention. (And if you're running AdSense on them, by the way, it's against TOS to run it on blank pages as well. And I'm pretty sure just having an unanswered question would qualify as lack of content)
* None of these sites have ever been hit by an algo change so far, and traffic was almost three times higher this year, FWIW
