I mean, on levels.fyi the 90th percentile in San Francisco is 500k. Most of HN is tech workers in the bay area.

The average person on hacker news is easily in the 90th percentile of software engineers, so yeah, I wouldn't be surprised if the most people here make somewhere around there.

The biggest confounding factor is the other fact that most HN users are startup founders living off ramen in Peter Thiel's garage, so that probably brings down the average some.
