I was totally down with this - a tight, efficient vector graphics format with After Effects integration, super - up until the point they said these animations were JSON files.<p>Huh?<p>Didn't I just read a whole blog post saying that one of their requirements was fast loading from disk, small bandwidth usage, etc? And that's what justified creating an entirely new image format from scratch, not something the internet is really suffering a shortage of already?<p>I know JSON is fashionable but that ending just seems kind of ridiculous. What's wrong with a binary format? Use Cap'n'Proto and mmap it! Saying numbers <i>represented as text</i> compresses well was the icing on the cake. No shit!
