From perusing the forums at Wikipediareview, it just came to my attention that Wikipedians actually debated if the list of pigs over 1000 pounds should be merged with the list of pigs. Note that these are not about zoologic classification of animals. No, these are about, well, "notable" pigs. In the wikiworld, "notable" means, well, "notable". It is an irreducible concept. If you don't understand what notable is, you don't get Wikipedia.
