Some recent topics I can think of... Facebook + fake news is about technology and user behavior, and also very political. Government use of surveillance technology is both technological and political in nature. Role of social media in elections has technological, sociological, politic aspects to it that can be discussed.
To me, being "political" is both what you're talking about, and how you're talking about it.
I enjoy reading what the HN audience has to say about the above examples. I'd be disappointed if they're considered too political and off limits going forward.
Interested to see how this experiment goes.
