Comment 2 for bug 389657

hbons also had a word on this, with a first draft redesign and first issues (e.g. how to manage the addition of multiple fonts). See http://www.bomahy.nl/hylke/blog/adding-fonts-in-gnome/
I added a link to this bug in the comments section of his blogpost; it may get people involved here.

Also, there are lots of upstream dicussion (I'll find the most relevant and it as a LP upstream tracker)

And the last one is a bit different but could be part of the scope: what about adding a right-click entry to do this?
