The iterative model for development seems to be one that more and more applications are taking. I don’t think it’s necessarily intended to create a more readily adaptable public, but that outcome is an apparent byproduct.

What’s interesting to me is that as people become used to that (frequent smaller updates to design & functionality), will they expect it everywhere else? Most college web design groups wait years between major revisions. If their Facebook-savvy userbase starts to get tired of the same design after a few months, that could have a significant impact on design processes across the Web.
