The downvotes are because it comes across as a shallow, middlebrow dismissal. An interesting and useful criticism would first engage with the strongest arguments of Rich Hickey (creator of Transit and edn). If you find something in his Language of the System talk (https://www.youtube.com/watch?v=ROor6_NGIWU https://www.youtube.com/watch?v=ROor6_NGIWU) that you either (a) disagree with (b) think XML solves already, I and many others would certainly be interested in having that conversation. Note that this doesn't mean the exposition of "Why Transit" can't be better, but that calls for constructive criticism on how explain the ideas better, or a question made in qood faith. What it doesn't call for is a hostile reply saying in effect "pff, already been done already, stop reinventing the wheel".
