Downvotes? Come on, the 90s were fantastic. I haven't heard of Fish before but what I said was meant as a supportive pat on the shoulder; projects like these are great. So whoever's pressing the down button, please, try to crack a smile, or at least stop ruining mine.
Comments which add little or no value to the discussion are discouraged by HN community mores [edit: the "avoid me too comments" has been removed from the guidelines but habits die hard]. The reason is illustrated by this subthread: such comments often devolve into metadiscussion about behavior and complaints about community norms.
The up arrow expresses support for the story. The delete link allows a person to revoke comments that don't merit upvotes. The edit link lets comments to be modified with supporting details, examples, evidence and rationales that contribute to HN'ers understanding and knowledge by extending the content.
That's more constructive than complaining about downvotes and implying that people don't get it.
I think the downvotes are because you completely failed to grasp what Fish shell is. It is a newer more modern shell than bash not some type of retro 90's toy.
