I'd say that's more or less covered by the general rule we've developed over the years for major ongoing topics (MOTs), which is to downweight followups unless they contain significant new information (SNI). Most likely yet-another-cherry-picked-AI-example posts don't qualify as SNI. If people see those on the front page they can flag them and/or let us know at hn@ycombinator.com.

The tech itself is moving so fast that there is a lot of SNI, plus a lot of good articles/blog posts/reflections on what's happening. I guess the goal would be to keep the highest quality stuff and filter out the copycat stuff. Which is which that is open to interpretation, of course, but it's not completely subjective either.
