Points can be gained by giving any/all questions an "UP" or "Down" on the Green Answer block, or by giving a question a star. These are gratuitous, self assigned. Points like "Best Answer" or Up points given by others are meaningful points. I know of the meaningless points I have, and wish I didn't have them. These are points I do not want.
Sure, I want a Mach 2 after my name, but I want to earn it.
