Don't be so quick to dismiss 'hacks'. Important innovations often start out in unrelated fields, or build on discoveries or solutions attempted in unrelated fields. We don't have to look too far for evidence of this: the Internet, the laser, and the computer were all important inventions that changed the world in ways its creators never intended them for.

I'd argue that innovation happens in widespread tinkering. So it could be true that most of the tinkering today happens to be on webapps. But it's presumptuous to assume that none of these attempts would result in innovations of significant worth to humanity.
