I sense that we could construct an amusing zoo of subcategories here. e.g. The Oyster: A species of Hoverboard that appears to magically parse natural language or generic web data but which on close inspection turns out to be a slick-looking wrapper around a rat's nest of Perl regular expressions which are being frantically updated by a harried group of hackers to deal with each "edge case" as it arises. The Turk: Like an Oyster, but without the regular expressions. The Esperanto: A Hoverboard that promises to help non-programmers write programs by using "natural" syntax that is "just like human language". See e.g.: AppleScript. The Gift-Horse Engine: A Twitter that is in fact virally popular, but only because it bribes adopters by giving away something below cost in an unsustainable way.
