All the arguments were the same over and over. I remember reading the same comments that would come up all the time, the discussion got old.

Plus the topics were very Linux, DRM focused. Digg had newer more interesting tech topics

This is a great reply. Real question: Why hasn't the same happened to HN? To be fair, there are some arguments that play out over and over again: SF crime & homelessness, Bay Area housing, US taxes, central banks "printing money", office vs work-from-home, feeling forced to adopt liberal social views / stances at a tech company (Black Lives Matter, LGBTIQ+), etc.

And somehow, there is still enough good, new content to keep the conversations fresh. Some of the best are when someone shares a personal story, then there are tens or hundreds of follow-up posts -- generally supportive or inquisitive.

HN works because of the effort applied to downvote garbage replies and keep the tone sober ond collegial.

I've had a number of replies get hammered, unfairly in my view.

Yet the signal-to-noise ratio benefits overall if we eat a little Type I error now and then.
