- Currently, the two leftmost links in the top nav both link to the Quarry front page. So they'reredundant.
- Logged-in users don't have much reason to go to the front page anyway--they can create a new query by clicking "New Query".
- I use the profile link all the time, because I often re-run or tweak old queries that I've published.
So... for logged-in users, make "Home" go to "My profile" instead of to the generic landing page.
