When you have a post that you want to embed onto a page, you now have a menu option on the post drop down (upper right hand, small arrow) that includes a new item of "embed"
When you select Embed Post, a pop up box will give you the code and the sample of how the embedded post will look like
You can now copy and past the code that you are given and use that in your Blog (switch to HTML edit) or other spaces where you can paste code into your programming.
For those of you who spend quality time on your posts inside of FB and want to encourage wider use of that effort, embedded posts may be a good option for you. They also allow you to share other posts from pages that you might want to blog about or comment on as well.
