Sure! Since I haven't sat down and thoroughly dug through the code, I'm not 100% on how to do this.

From looking through the link model file and how urls are generated, I believe it's something like -
```
if thing.is_self:
   d['link_url'] = thing.make_permalink(thing.subreddit,
                                               force_domain=True)
else:
   d['link_url'] = thing.link.url
```

Is that accurate? I'll try to test this sometime tomorrow if I dont hear back, thanks.
