It's essentially a website builder that uses Adobe Illustrator for creating pages.
The results so far have been really promising: - building websites is extremely rapid - very little debugging or verification is needed - it's easy to create beautiful content
Techniques that were trivially easy for me 30 years ago in print are still impossible in HTML. With SVG, I can just design the page without worrying about interlocking invisible boxes.
You can try it yourself — it's free, but you'll need to create an account for the hosting part.
The only tool I could find to create the SVG's was Adobe Illustrator, because it enables linked images and fonts, like regular HTML pages.
As far as I know, no other SVG editor except for Inkscape does this.
For now it's Mac only.
