Sharion, that's a good system! I realized last night while converting an older article that I'm going over my work way more than three times. But part of that is the fact that I'm becoming anal about whether I missed something and I am trying to use such a fine-toothed comb that I start and re-start over again after I find a mistake (or even just to tighten the wording.) I suppose I'll get better at this as I go, but I think I've always been this way with my own work. Part of me thinks I'm wasting my time, but the perfectionist in me hardly cares. I pray for the day I can get good enough to do it your way.
But that's what writing is, isn't it? 20% creative and 80% editing? I hear all those sayings about writing your heart out and then cutting out at least 20% to make it GOOD writing. Whenever I need to think about the impact of my words, I think of Hemingway's famous short story- "For Sale: Baby shoes, never worn."
Jadedragon, you've just made my year. I still think that it's a healthy fear for new writers to think there's a 3-strikes rule if for no other reason that it will help them understand that CC is not a "content mill" and it demands high standards. That's what we want, isn't it? As someone who really does strive to make every piece as perfect as possible, it is a relief to know I won't lose out on this opportunity because I misplaced a comma for the "last time."
And OldMan, I think you should try to be as stylistically independent as you can while still staying within CC's structure. Honestly, there is not a single thing in the guidelines here that isn't applicable to scores of other kinds of writing, even academic writing. But I believe strongly in being proud of your own voice, as long as it's grammatically correct.

At least in a marketplace like this one. I'm sure CC would hate for you to lose out on a sale because a client got distracted by some odd error or wording.
Also, I am young (to many, though sometimes I feel 40 in my head, lol), and I may be experienced. But I have SO much to learn.
One of my favorite quotes is, "Education is nothing more than the progressive understanding of your own ignorance." I feel like the older I get and the more I do, the more I realize that I have a looooong way to go before I "get there."
