David Weinberger asks why some things feel on the web like 'ours' while other things feel like 'theirs':

Put aside for the moment question of what's legally ours on the Net. Instead, consider what's ours in a less explicit and less rigorous sense. Google feels like ours (even though it legally belongs to its shareholders) while Microsoft's new search site feels like theirs. Weblogs feel like their ours while online columns do not.
