The $100 is for someone writing a fully-working parser that handles real-world HTML5 pages, without reusing any existing implementations. Building an entire new parser is (obviously) much easier for strict languages (e.g. JSON) than for lenient languages (e.g. HTML5). Which is the problem I have with HTML5, JS, and many similar technologies – they’re so lenient that almost everything is broken instead. We might as well write websites in english prose, it wouldn’t be much harder to parse.
