I'll toy around with this.

I have a github issue tracking sorting (as requested by another user) https://github.com/stackernews/stacker.news/issues/15

I'll drop a link to this comment in there.

Considering how this could work. You could have a new "nav-item" called "top" or "popular" and under that would be 2 dropdowns that user can choose from 
- **Popular**: Today, This week, This month, This year
- **Created**: [Today], Any time
The Created would have 2 options, the first one would match your "Popular" selection and the other would be "Any time". The selection for both would be nice to persist on client (e.g. localStorage). 

This serves 2 purposes, sometimes you just want to see the freshly created news only. And sometimes you want to see what has been boosted recently. This may be a bit harder to grasp by just reading this definition, but try playing with it in action, it becomes intuitive ;) @k00b FYI.
