This includes most blog integrations, eg. being able to configure Wordpress to post a plug on your personal FB when you write something in your blog.
Although, any site using their JS API can still get your name, email and a unique ID, posting is now restricted via a FB modal or pop-up (which is blocked by more recent browsers).
I think this happened in May/June of this year, IIRC.
I don't want Facebook, nor Twitter. Just take my email address and send me your content, or offer an RSS feed.
EDIT: Anyone know if this kills Buffer and other social feed managers?
Only temporarily. Once folks move off of Facebook and onto something better, they'll realize that this was a Good Thing overall.
While that would be nice, I'm not holding my breath.
