Is there a discussion for the arguments for and against pay-per-view when using font? Have their been licensing schemes for typeset work where the printer had to pay each time a person opened the book using said typeface?
From the description:
"It is also available in web font formats for self hosted websites (up to 10K monthly pageviews on average)."
You buy a license for your website. Large websites (with more than 10k monthly pageviews) need to contact them for a license.
For a blog or newspaper it may be obvious, for web applications it can be very hard to determine.
1. Do I average more than 10k page views a month right now?
No: Buy license good up to 10k page views per month. Yes: Contact them about a bigger license.
You're not asking how to measure your own page views, are you?
