On Goodpoint, the point is the statement you're trying to persuade others about. It is the essential claim you want others to agree with in your argument.
It is equivalent to when someone says, "What's your point?", when you are explaining your view to them. The purpose of making any argument is to persuade someone of the point.
In the Goodpoint editor, the point is simply the title of the top-most idea in the argument you have selected. It is shown at the top of the page in bold, larger font.
TK: an illustration showing the point relative to the rest of the outline. It would be good if it can also show that the point is the first idea's title.
Pro tip: the point is determined by the idea you pick. No matter what idea you
pick, when you edit it on Goodpoint, its title will be the point!
Another pro tip: the point is a relative concept. When an idea is selected, its
title is the point. But that same idea might be used as a reason in a different
argument, in which case its title is not the point (its just support).
