I've noticed what may be a pattern in many HN discussions: a particular philosophy, such as stoicism, makes the rounds. (I would expect there is a common cause, such as a popular lecture, but that common cause is not always clear.)
Given that we have many thousands of readers here, I think it is better to have a diversity of philosophical explorations (rather than intense interest only on a few).
For example:
A. There are variations within utilitarianism that Mill lays out but does not resolve. For example, 'rule utilitarianism' or 'act utilitarianism' [1]
B. Another level out, there many theories of political economy that contrast with utilitarianism.
C. Political economy is a fascinating area. Many people already read Milton Friedman, so I often recommend reading Arthur Okun's "Equality and Efficiency: The Big Tradeoff" as a counterpoint [2]
D. Go another level out, and you will find many theories of ethics that are worth examining.
