David - it so happens you've written about something that my day job involves (I run my own website design/marketing company). What I would say about Web fonts is go slowly, test thoroughly. If you are on a Mac, using a modern browser, some of the issues with Web font won't be apparent to you. Here's a blog, by myself, on the subject: http://www.webdesigndev.com/web-development/web-unsafe-fonts-–-common-issues-and-workarounds

Best, Peter
