But does it have to be on the Internet for all to see?
How else can you get other people to comment on it, if they can't see it?
Once you fix the mistakes, what's wrong with leaving it up?
Plus notice no mistakes were called out. It was just "don't buy parts from amazon".
Is only the public Internet remaining as a medium of communication with your peers?
Of course not. One can use carrier pigeons instead.
I see - the author stood behind you and forced you to not only click on the article, but this hacker news thread and also forced you to comment too. Yes, that is horrible!
