One thing Foundation is doing that I haven't seen done anywhere else is Foundation for Emails (http://foundation.zurb.com/emails.html http://foundation.zurb.com/emails.html).

There are so many quirks in Outlook, Gmail, etc that its nearly impossible to keep up, so it's great to have a team of people dedicated to abstracting it away for designers.
