It doesn't seem to have ever gotten very much use at all; I can't think of any famous Waldos except for Where's Waldo. That, to me, that being tied so tightly to one single character, is a huge strike against it right there. Also, it just sounds comical, like a big goofy dog who knocks things over just trying to get from one room to another.
