It's not weird, it's intentional, and desired. The short and to-the-point answer is marginally more helpful if it arrives sooner, because it solves the problem quickly, so it will tend to earn a little more reputation. Coming back later and embellishing the answer with details, sample code, whatever, and you will earn a flood of well-deserved reputation. Doing both--providing a quick answer and then embellishing the details so that the Internet has a great resource--is the ideal outcome and therefore rewarded with the most reputation.
