The issue with the recent rise in Show HN submissions, from the perspective of someone on the ‘being shown’ side, is that they are from many different perspectives lower quality than they used to be.

They’re solving small problems or problems that don’t really exist, usually in naive ways. The things being shown are ‘shallow’. And it’s patently obvious that the people behind them will likely not support them in any meaning full way as time goes on.

The rise of Vibe Coding is definitely a ‘cause’ of this, but there’s also a social thing going on - the ‘bar’ for what a Show HN ‘is’ is lower, even if they’re mostly still meeting the letter of the guidelines.
