Why twitter is a load of crap?

The answer is simple. After viewing the "what's it all about" video on the twitter home page, I came to the oh so obvious conclusion that twitter is pretty much the same as only having the status updates on your facebook page and nothing else. Why use twitter when you can use facebook and have so much more things to do instead of pry into the lives of everyone you know? Or don't know and met once at party in such a drunken state that you actually think they were awesome enough to accept their friend request.
