URL field missing in profile

Looking around a bit I've just noticed a glaring omission from the Vox profile page: No URL fields.

We've got fields for half a dozen instant messengers -- AIM, Yahoo, MSN (does anyone actually use this?), Skype, Jabber (for some reason labeled "Google Talk") -- plus e-mail address, but no web site URLs. Intentional or an oversight? It seems like a pretty obvious thing to forget. Assuming Vox is intended to be a social hub of sorts, I'd expect there to be spaces to list multiple web sites, as well as Flickr usernames and the like.
