As much as I want code reviews, I don't think this site is the best format for it. Code reviews to me are either focused on some specific lines of code ("You use $i here but $j there - by intent or mistake?") or on a larger concept ("Why did you choose to solve it this or that way?"). They require discussion, back-and-forths, while the comment system here is intentionally limited.
I know all of us want to do and request code reviews, and we must do something with all that positive energy, but I suggest we try to find (or create) a dedicated system to handle this, since it is a completely different beast than the "best answer floats to the top" style of Stack Exchange.
