Not to knock on you, but I'm starting to see this is a trend. I was on the hn irc channel, and numerous people complained about the same thing. That you're always very willing and ready to offer support here on HN by saying "Sure, just email me!" but when these folks do email you, they are ignored. I don't know if this is a clever PR strategy to contain and direct fallout to a private medium so it never sees light of day, or if it was a genuine mistake.

I think and hope it was the latter, but the frequency with which this seems to be happening starts to suggest it may also be a little bit of the former. E.g., just in this very comment thread there's a handful of people claiming you never responded to emails even after explicitly asking them to email you.
