I've used single line CSS for 2+ years now. I find it better at both reading and inserting/edit (I find it weird to read/write Multi-line ones). I used to sort by layout-appearance (important layout first, than appearance), but have now switched to A-Z sort of properties for maintainability (if others have to look at your code, you have to think about them). However ocharles is right about the fact that it screws diffs (as long as they are per-line oriented).
