Jun 20, 2012 at 22:05 comment added David Roberts My question is partly sociological, in that calling a simplicial object contractible when there is no model structure (of any flavour) is perhaps stretching the imagination. One can of course write down these definitions. If it is well-accepted such things can be called contractible, then I am satisfied. I can only guess that we think of them as being contractible as objects in some category with a class of weak equivalences. And you are right about all the stupid terminology - there was a second more complicated question in there that didn't quite make it out, and I should have cleaned up.
