Font changes / Cantarell

I know that Gnome is using Cantarell as its default font, and it seems that something has changed in Fedora to make Cantarell the default font for all desktops. I heard from the KDE SIG this morning that there is some confusion as to whether that was intended to be a global change, or a change only for the Gnome desktop.

I don't pretend to have a clue when it comes to fonts or the fontconfig stuff -- but I'd like to kick off this discussion so that there is less confusion and that nobody tries to ascribe to malice that which can be explained by miscommunication. Is there someone that understands the change that can fill me in on the missing details? -- Jared Smith Fedora Project Leader
