The social module provides a way to have social sharing buttons at the side of your home page and posts and or pages, and also a short code so you can place the sharing buttons above and below posts too.
You can automatically have the floating buttons disappear on narrow displays too. You can style your own social buttons to make them any color you wish.
The social module also provide a way for you to use off site images as featured images – s if you host images at Amazon S3 you can still use the featured image facility of WordPress.
Also we add explicit Facebook Open Graph forms so you can specify a different image, title and description for Facebook posting than for your SEO titles and descriptions. It might be that you need a more robust sales message on Facebook that you would choose for SEO.
