Remember that it was actually Microsoft who created and pushed for the RTF format as a common interoperability file format for word processing documents. This was way back when Microsoft and its Microsoft Word™ was the newcomer against the established giants in the field of word processing: Word Perfect, WordStar, etc. Of course, when Microsoft Word gained popularity (through no direct advantage of its own – it was using its coupling with Microsoft Windows, which the competition was wary of), then Microsoft lost all interest in RTF standardization.
Snap is good, and useful, but it's not that useful, it's just a tiny library, and a bit of a wasted opportunity IMO. With fairly crap documentation beyond the basics. I would love it if there was movement on this, a better SVG workflow from Illustrator -> Web would make my life a lot less frustrating, but v0v it's Adobe and they either move at the speed of a geriatric snail or they stomp all over tools I find useful
Adobe has been pushing SVG and the tooling hard. Illustrator is great at SVG. If they want to kill it and replace it with a proprietary format, they're doing a fucking awful job.
