At present, there are a number of plugins for WordPress which improve your website. I find this Wordpress Plugin called Quoty, a free plugin which makes easier to share the selected text through the major social networks.
Although this is a simple plugin, no doubt that can be useful for many users. Once installed, its operation is most simple. As you can see in the picture accompanying this article, you only need to select the text you want to share and pop-up Automatically to allow us to choose the social network for sharing.
Twitter, Facebook, LinkedIn, Pinterest and Google + platforms supported by Quoty.
Regarding the installation process, you only need to download the plugin from the official website of WordPress and follow the instructions prepared by the developers.
