I find the posts are usually better quality than the standard HN submission, but even more the comments on HN are better. A complete generalisation, but those replying to data tools posts are more thoughtful in their comments and exhibit less absolutism than I see on software development related posts.

I imagine one factor is that there are lots of OSS projects that are simultaneously startups in the data space these days.

Higher signal-to-noise, at the least.

Data engineer here. Lots of great posts on data stuff is one of the reasons I love HN.
