I do think you should make this default to showing the top stories instead, given there is no way to vote, it's better just to show stories that have already been voted up. Also, I think you should use their idea of an exit option at the end, I couldn't find a way to exit save Ctl-C.

It would be really nice to be able to filter stories on a query string too, as then you could easily search for stories about Go for example (wish HN had better metadata for this, but it would still help).
