Neat, but I don't understand why Adobe would do this. I already use Adobe Typekit, and $50/year gives me access to a huge library of fonts at an unlimited number of websites. For my purposes, I'm tempted to stop paying even that totally reasonable, meager amount and just use this free offering instead.

After following most of the links on the page, I can't find any mention of limits on pageviews or traffic. On the surface of it, that makes their free offering a little bit better than their paid offering.
