Hey folks,
I've followed up on this and unfortunately the links won't be making a return in the foreseeable future. Google decides how visible any given site is online and they penalize sites for having multiple links to the same content, even on the same page.
Basically, if they see a breadcrumb at the bottom of a page, they count that as having multiple links to the same content, even though this is actually an identical link that's exclusively designed to let folks quickly get back to the top of the page, and they lower the rank of where that site appears in searches.
While we'd absolutely prefer they not do that, they do, so we had to remove those links. You can still use the Home key on your keyboard to go to the top of whatever page you're viewing, regardless of the site, so at least there's a workaround.
I apologize for the inconvenience and if the rules change on these things, we'll absolutely revisit the change.
