That is the main way I interact with hackernews.

Before using it, I was checking the website more frequently, fearing I might lose some popular post. Much like other social apps make you do - facebook, twitter, reddit...

But with the 'top 20' and 'top 10', I know I can be 2 days without checking it, and I will still see the most popular posts.

I don't like when apps incentivize/reward time on the app. It's the same reason why I've never played MMOs.
