Prevent Facebook from tracking your users, but use the power of Facebooks social plugins on your WordPress page anyways. That is, what this plugin enables you to do.
Finally I got to rewriting my first WordPress plugin. Looking back it was a great experience, but due to not researching enough I wrote it after an old practice, thereby not having multiple instances of it. It could only appear once on the page.
I have created a little WordPress plugin in the shape of a widget, which allows the user to display an excerpt of a page in a sidebar area of their choice. It in fact now is online in the WordPress Plugin repository: Page Excerpt Widget. Feel free to test and rate it!
