1) When I participate in public forum - I imply that I am looking for all unsolicited advices I can get.
Getting unsolicited advice is my main goal in discussion.
Receiving unsolicited advice is one of the best ways to learn about mistakes in my mental model of the world.
When you try to suppress such advice-giving culture on HN -- it reduces my chances of receiving my share of advices and reduces the quality of my communication on HN.
2) Even if advice is formally addressed to somebody else -- I frequently can learn from it anyway.
The author of the advice is well aware that his advice has multiple recipients -- even if the author formally addressed only a single story-teller [to make his advice easy to understand for all readers].
