UPDATE: After reading through the comments from my previous post about starting a layout critique, I wanted to make one thing clear:
These rules will only apply to the layouts that I post here in the blog that are specifically marked for layout critique. We will focus on 1 layout per week. Of course these tips can be used when you are commenting on layouts in general, but since it does take time and effort, I think if we focus our efforts the payoff will be greater. If things go well, I can always increase the frequency of posting.
