I find backing in to be a bit ridiculous in some cases.  I only do it if it makes things easier, such as unloading the rear closer to where I need to be or in the direction I'll be going (when I have a lot of stuff or something complex to unload).  I find it generally unnecessary with no benefit otherwise.  I do remember that in some big cities there are certain parking lots where you'll be broadcasting your sexual preference based on how you park.
