Don't you think that this lacks courtesy to post a comment rather than just email them? I mean, if there were a reason (and I can think of at least 3) then you just ignored it.
Yes, but there is a difference between being curious and finding out whatever you can, and posting the results of that search to a public forum - especially when the word "secret" is in the contact email address. It just seems a little unnecessarily unkind.
I suspect it never really occured the grandfather - because there wasnt really any secrecy, this is a community that generally scoffs on secrecy as "a bit silly really" and there appeared to be no harm in spreading possibly interesting knowledge.
Not deliberately malicious I am sure.
I was going to post it too but checked myself at the last minute.
Sorry if I broke HN-etiquette, I'm rather new around here.
My impression is that "Ask HN" questions call for more nuanced interplay, while links are intellectual free-for-alls where it's assumed that everyone (including, if not especially the OP) comes armed for probing discussions.
Sincerely speaking - should that not be my expectation? Feel free to e-mail me as well (unlike stealthyc2010 my e-mail is listed).
