I would go even further and make `profile` mandatory, and assume it's *always* a profile instance so there is not change of hitting the database from this method. There are only 7 uses of this method in the whole codebase, so I assume it would be easy to change all of them.

```
$ ack link_to_homepage app/ plugins/ -l | wc -l
7
```
