I would say Oblivion and friends deserve some attention (like, an article on our wiki), in part because "Bowers is a god" and he is a recognizable figure in googology, but it should only be considered as a (failed) attempt at creating a number (at least for the time being; Bowers might get around formalizing it). We shouldn't consider it to be a "proper googologism".

Claims along the lines "this number would be bigger than BIG FOOT/whatever else if it was well-defined" shouldn't be used, because it is not well-defined. The same can be said about "the largest number definable in googolplex English words" - if it were well-defined, it would stump others, but it is not. Go ahead and make it well-defined, then we can talk.
