I am a StackOverflow user for almost two years(Proud to be so). But my reputation has not been increasing much. It is 3083 at present.
Although I know why that is so. I don't find enough time to go on StackOverflow. With work and family, I am not able to visit it every day. I try though to visit it on alternate days. That too for 2 may be 3 hours. I see people being member for just 3-4 months and acquire a huge reputation which really surprises me.
My question is how can I efficiently utilize the hours I visit on StackOverflow to increase my reputation?
