I have been looking at WordPress plugins, and I found this great new Social Quote plugin. It allows you to select portion of the WordPress Post or page to share on the social networks. Go ahead try it. Select some text by left clicking and dragging over some text on this post and then you will see the Social Logos.
Here is the link to the WordPress Plugin: https://wordpress.org/plugins/quoty/ I know you will enjoy it as much as me!
