The number of similar photo sharing sites on the web are miniscule to the number of web sites on the web, and the draft spec currently reads: "In certain /rare/ cases, the image is simply a critical part of the content, and there might even be no alternative text available. This could be the case, for instance, in a photo gallery..." Current supporters of the optional @alt often refer to this as the edge-case exception, not I. Wikipedia provides the following definition: "An edge case is a problem or situation that occurs only at an extreme (maximum or minimum) operating parameter." [http://en.wikipedia.org/wiki/Edge_case] and Merriam-Webster's dictionary defines "rare" as: "superlative or extreme of its kind" [http://tinyurl.com/5kj7fm] Given the rarity (quantity of unique sites, not unique users) of photo-sharing sites (which BTW, *could* include the ability to provide @alt, but currently do not do so) and the even rarer instances of Rorschach inkblot tests on the web, it becomes an exercise in semantics to define edge-case here.
