answered Is there a (satisfying) proof that cellular cohomology is isomorphic to simplicial cohomology that doesn't use relative cohomlogy?

comment Identifying a Hopf algebra cohomology theory
It seems to me that the natural action, under which you would be looking at a cobar construction, would just come from the diagonal on the left most tensor factor H.

comment How much of homotopy theory can be done using only finite topological spaces?
Whoops. Thanks Lennart. I didn't know Raptis's paper and I think it is the same model structure. So here is something new. For a discrete group G, the category of G-posets has a model structure Quillen equivalent to the standard model structure on G-spaces or G-simplicial sets.

Since I wrote that answer, Inna Zakharevich and I have defined a model structure on the category of posets and proved that it is Quillen equivalent to the standard model structure on spaces or simplicial sets. Thus in principle one can do all of algebraic topology with posets.
