These are super handy @pandorasbox when you use the Twitter link, I always hashtag #Steemit and add @steemit to the end of the post to get more traction.
Using Facebook post, you can post to your page (or business page) and then go back and post to places like We Love Steemit (once you are accepted by the owner of that page).
For exceptionally good long detailed posts such as @jerrybanfield whitepaper post suggestion I post that to LinkedIn as well.
Quick and easy sharing is available, everyone just needs to learn to share.
