Facebook not allowing post to WordPress- oversight?

Twitter can publish to here in a side bar, we can publish to Twitter from here….

So why is it Facebook isn’t on board with WordPress just yet? I mean sure- we can link BACK to FB- but what about FB linking back to here? 

Seems to me a massive oversight for FB when people with businesses would love to be able to back post to WordPress to keep their blog fans informed… Sad face Facebook, Sad face.
