or like search engines - a bunch of stuff can happen in the 
background to make it easier to find potential matches and things, 
but at some point a human may be asked to help make choices - goal of 
machines on the web aren't always to get 100% correct answers but to 
help humans with their needs in managing this humongous info space

btw, although I am probably one of the main proponents of the many 
linked ontology vision, and think the eventual success of the SW will 
reside to a large degree in many linked vocabularies being used by 
combinations of humans and machines, there's a lot of value in the 
near future for single ontology applications, or the use of 
ontology/instance mappings (for example in photo search applications) 
and thus I don't think "the success of the semantic web" hangs on the 
cross ontology stuff -- the eventual ubiquity of the SW probably 
does, but we have a couple years till I expect to see that :->
