Why don't we have a "reply" feature, that alerts on every reply to a comment on any thread?
Its very difficult to check manually by navigating through own comments, especially if there are comments on more than 2 threads in a day.
I don't want to compare, but lobste.rs have implemented such a feauture and I find it very useful.
EDIT: Yes, it still works.
It discourages this sort of thing, https://news.ycombinator.com/item?id=24377372
There is also a timer expressly preventing you from replying too quickly to each other.
There are many quotes on questions, like “better to ask and be thought a fool for five minutes than to remain a fool forever” and the likes, but to me, there is something deeper than that. Asking questions often reveals a lot more information than just the answer to the question, almost regardless of the situation.
However, it is always worth doing a search before asking questions rather than receiving a spoon-fed answer (or a Dang "discussed Previously At:) comment but - here ya go ... follow the Rabbit Hole of Links to Truly Understand the 'Why'.
Search is your friend when it comes to things like 'why doesn't HN do x or y?'.

Personally, I'm glad it doesn't exist. I don't expect HN to be like every other forum out there.
