Ah, that makes sense. Any idea on what causes it? I did try submitting a few times and received the message "You're submitting too fast" (even though it had been days since my last submission).
PS- I came across one of your posts yesterday and today as well. I like reading your stuff man-- keep it up!
I think it's the little things like that that can make a huge difference. Even if it's just a short, quick reply like you mention, it is still very satisfying to at least be acknowledged by someone!
Also, on a slightly similar note, I remember reading that the guys at Pinterest sent out thousands of emails to the initial users of their site. Now, I'm not saying that that was the sole reason for Pinterest's massive success, but it definitely didn't hurt 'em!
