I have to question "perfect functionality".

Even 25 years ago, on Slashdot I could tell it not to show comments with less than a certain number of upvotes, and thus filter out a lot of the dross from busy conversations.

I can't do that on HN. I can do something like it on Reddit, although I know of no "expand all" functionality, but on HN it's all or nothing.

That is imperfect to say the least.
