Will other people see my home address when they view my post?
No. Your home address will NOT be shared with other users.
When someone views a post of yours, if they click "view map", they will see the general area that you are located for basic directional information. The map only uses your postal code in order to do this. That way no one can zero in on your home address.
If you prefer, you can even just use the first 3 characters of your postal code to make it an even broader location.
