:( No hyphenation, kerning or leading. Knuth and Liang solved this problem decades ago. I dislike like having to hack it with Javascript. That lack is what makes web typography ugly, even in this demo.
This is an interesting demo, but it seems to focus more on "whizzy" things, instead of fixing more basic problem.<p>Now, in their defense, I thought the baseline alignment idea was pretty good. But if you look at their first demo of the "callout" text, you'll note that there are horrible rivers (open spaces) running through the type, making it look all clunky.<p>What's really needed is a straightforward wysiwig layout tool (like Quark or Illustrator, for example) that can generate clean CSS layouts.

Web kit is a fail that has a tiny percentage of the browser use. Safari has too small of a % to be relevant (except mobile obv), and Chrome just screws up too many small things (despite being an otherwise overwhelmingly better browser than the alternatives).
