Oh, I agree with feature creep being something you have to watch out for, and there are definitely examples where adding everything and the kitchen sink has led to virtually unusable products/services (remembers that browser screenshot showing IE with about 20 custom toolbars) But it's a balancing act overall. You need to know what the users will actually use and what they won't, prioritise things that more of the userbase will get some mileage out of, and move away from the idea that simple or complex is necessary better/good for any product.
