Ask HN: How has HN's language changed over the last decade?

I am working on a computational analysis of the HN discussion corpus over the last 10 years, interested in how the community's discourse has changed, and in the trajectories of individual users within community change.

I am interested in intuitions (and examples, if available) about:

1. How HN's community language is distinct from everyday talk and from other online communities 2. How HN's community language practices have changed over the past decade 3. How specific word meanings have changed over the past decade
