Emphasis is my own…
As a Typekit user, you’ll have access to our library of high-quality fonts. Just add a line of JavaScript to your markup, tell us what fonts you want to use, and then craft your pages the way you always have. Except now you’ll be able to use real fonts. This really is going to change web design.
Also worth checking out, Jeff posted a preview of the Typekit home page yesterday. Looking forward to how this will change typography and design for the web.
