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).
