I notice other people become discouraged when nothing seems to be happening in a shorter time frame.
I went through the five stages of grief after submitting http://arclanguage.org/item?id=12657. It took me literally weeks to get right, and it sat at I think 1 point for nearly a week (with just evanrmurphy's positive comment[1]).
But eventually I realized much of what you said :) I have more realistic expectations now. Points are nothing, and responses come in time.
[1] While evan was active you could tell when he'd seen something because it would go to 2 points :) (without suggesting that he upvoted everything)
Evan would often articulate agreement or admiration even if he had nothing to add, and it was useful. But I'm not sure we should all do it.
Perhaps all this is a sign that we need a back channel.
