| Dec 12, 2009 at 17:58 | comment | added | Reid Barton | I don't know whether this is helpful or confusing, but every ordinary (co)limit is also a homotopy (co)limit! (It is a homotopy (co)limit in the topological category formed by taking the ordinary category and giving its Hom sets the discrete topology. Note that this is not how we normally make Top into a topological category.) | |
