In the end, HN comments fall prey to this truth and you see a handful of positive comments, with the majority being criticisms or "I wish this did X". No one person is to blame. Its just the culture of technologists today.
If you explain why, they either still don't understand, or don't agree.
If the first iPhone had been presented on HN/Reddit/Twitter, everyone would criticize the lack of physical keyboard.
I do not see how the comparison to the iPhone here stands.
Difficult to understand is often threatening.
Criticism is a popular response to threat and is the form of reply that requires the least understanding.
P.s. it seems rather likely the op is Victor Taelin, they mostly submit his tweets and gists.
Who are you rooting for, exactly, newcomer?
P.p.s. Victor Taelin just happens to be the most recent committer on this submission, imagine that.
