What is the right way to ask for feedback twice?
petesalty: A situation I've run into occasionally is that I don't do it right the first time, either I don't ask the right questions first time (something you often don't know until you've asked them) or I ask the wrong audience. I did it here on HN a few weeks ago when I asked for criticism of our glunote app (shameless plug: http://glunote.com). 
I didn't do a very good job about defining what I wanted to know, so I asked again, but this time with more explanation. When someone bought up the previous post I simply admitted that I'd screwed up the first time. I really think that most people, especially in a community like HN, won't hold it against you if you admit you did something wrong and ask for help again.
