Cloud.typography
Yesterday, the guys at Typography.com introduced a webfont project they're calling Cloud.typography, and it looks fantastic. This appears to be their answer to services like Typekit, and includes the entire H&FJ typeface collection.
You know how the default fonts in Check the Weather and Vesper are Idlewild and Ideal Sans, respectively? Yeah, they're both included with this service, along with a lot of other great options. They've got all kinds of other neat features too, so go check it out.
Pricing depends on the number of pageviews your site gets, with basic plans ranging from $99-$299 per year and larger plans from $50-$300 per month.
