In Facebook, to limit a post to a list, near the new post field you click the lock and downward arrow icon which displays a drop-down of choices such as "Everyone", "Friends", or "Custom". Click "Edit" next to "Custom". This brings up a modal box. In the "Make this Visible to" section, under "These People:", from the dropdown select "Specific People...". This makes a textfield appear. Type the name of the friend list (hopefully you have the names of all of your lists committed to memory, or at least the letter they start with) and a typeahead will display suggestions. From the typeahead suggestions, choose a list by clicking it. Click "Save Setting" to exit the modal box and return to the post editor. Hover over the lock and downward arrow icon again to display a tooltip of what lists the pending post will be shared with to confirm you have done everything correctly. Create the post and click "Share". So Facebook does have the option but it is hidden away below 'mystery meat navigation' [1] and is generally not at all intuitive for the average user. Google+ is receiving (deserving) credit for the concept because the implementation is present and forward in the UI.
