Thanks condra, very nice post indeed, i am thinking the same thing the other days. Sometime when a stories will lead a further question and thinking process and thay you will need to reward good comment if they are contributing to the stories. But comments do seem getting too little reward for now. So like you, i also reward early and good comment whenever i feel they are very useful to others.
