As a general rule, for me, the barrier-to-entry for online commentary is too low for genuinely worthwhile "longer term" discussions to occur. The vast majority of responses are "automatic" rather than reasoned and thoughtful, even in the limited cases where the commenter is otherwise "sufficiently competent" to contribute meaningfully. Shallow, reflexive engagement (especially from a "large" number of participants) has no actual value except to platforms needing eyeballs for ad revenue, which isn't the HN model. So.
