I'm hearing a lot of people talk about "dark posts" and touting the fact that it won't show up on the page as a great benefit.
But regular newsfeed ads don't show up on the page either, so I can't figure out what all the fuzz is about.
What's the advantage of using "dark posts" over regular newsfeed ads? Is it only the fact that the format is more flexible, allows for more text etc? Is that it?
