ERA404

This plugin operates by scraping an Author Post Activity page (e.g.: https://www.linkedin.com/today/author/[author]) to collect information about the author(s)’ LinkedIn articles. 
The properties of these articles are then sanitized and saved to a new table in WordPress, preparing them for output into your widget. 
The widget can be positioned in sidebars or footers like any other feed.

Selection Sharer makes it super easy for your readers to share your content and drive new visitors to your site. With Selection Sharer, any visitor on your website/blog can easily 
highlight any part of your content and share it immediately on Twitter, Facebook, LinkedIn or via email. Ultimately, the more your readers share, the more new traffic your site will get.
When a visitor highlights some text on your WordPress website they will be presented by a Medium like popover menu to share their highlighted content. This plugin supports both desktop (with a pop-over) as well as mobile devices (with a pop-under). This plugin is made possible by the excellent work done by <a href="https://github.com/xdamman/selection-sharer" rel="nofollow ugc">@xdamman</a> and is based on his code.
