Dive summary: 

• Facebook has announced that its posts are now embeddable, a function that comes a bit behind YouTube, Twitter, Instagram and other social networks. 
• Unlike many of the other social networks, Facebook posts are only embeddable on sites that have installed a plug-in; so far, that list includes only five sites: Bleacher Report, CNN, Huffington Post, Mashable and People.
• While the plug-in may seem like an inconvenience and hurdle to more sites adopting the embeddable posts, it does have one advantage—with the plug-in, users can comment and interact directly with the Facebook post on whatever site it is embedded without heading back to Facebook. 

From the article: 

"The social network announced on Wednesday a feature for embedding its content on other websites. The feature, which is only available on public posts, can be accessed through a drop-down menu on the right-hand side of picture, video, or political rant a user wants to use on his or her website. As with Twitter and YouTube, from there it's only a matter of copying and pasting a line of code."
