> high-literacy communities like HN [..] low-literacy communities like facebook and reddit

I see this sentiment a lot lately, and I see your HN join date is similar to mine. HN is more mainstream than it used to be, for better or worse. There is a lot more overlap between commenters on HN and Reddit nowadays, especially in certain categories of subreddits.

Personally, I lament the web being a high-literacy community.
