Twitter and Facebook look at value in orthogonal directions. On Facebook, the importance of every post is dictated by how much interaction it generates. This is very visible: comments and Likes are listed on every post. In a hurry, you can decide a post's value by how many people have already interacted. Liking a post keeps the interaction within the OP's profile page. By scrolling through someone's profile, you get a feel for how popular they are within the service. On the other hand, the value of a Tweet is proportional to the number of people who see it. This is sometimes difficult to guess when inspecting the original tweet, since Twitter does not track old-style Retweets. It doesn't matter though, since your message is broadcast to dozens (or hundreds, or thousands) of people you didn't reach by yourself. The threshold of quality is a little higher with a Retweet: in a sense, you must be willing to say the original Tweet yourself. But a popular Tweet can reach more people than a good Facebook post.
