Explain the OGL to me

Here The AD&D Grognard expresses concern over the lack of proper use of the OGL and where it will lead.

I'm not sure when it is appropriate to use and when you can give it a miss.

For example:
Should I have a OGL page for monsters that use a Swords and Wizardry style stat block, but are largely my own creations such as in these posts?

How about spells, like in this post?

What about my own house rules that use common gaming concepts like hit points?

Does the fact that I'm not looking for cash here make any difference?
