    looking again over this entry, I notice that the “Example” of bipointed sets (here, by Anonymous in revision 28) is misleading, as the conclusion, as stated, has nothing particularly to do with the nature of 2\mathbf{2} but just with the fact that the endofunctor is constant.

    Or maybe I am misreading the intended message (the wording seems odd, too).
