Does the HN community have an upper bounds?

HN continues to be a mainstay of my daily reading, and has been for some time. However, as I've only just recently [re]registered, I found myself curious as to whether it will [continue to?] suffer a loss of novelty as the community here grows.

Is there an upper bounds to HN's community size, especially considering its lack of "sub" communities? Or is this something that will keep the HN culture strongly ingrained over time?
