Twitter Vs. Facebook
Here's the dirt on how these objects relate to one another:
Facebook invented the concept of the personal feed, with users posting updates about their lives which are broadcast to their friends. Twitter took this idea and ran with it, making it so that not just your friends can see your updates, but the entire world.
A crucial difference between Twitter and Facebook is that Facebook imposes a 5,000 friend limit, and both friends must agree before a connection is created between them. Twitter has no follower or followee limit, and you can follow anyone you want, without getting their permission. The reason this is important is that it allows people to follow famous celebrities, some of whom have literally tens of millions of followers.
