To me, the value of Loopt isn't so much that if you want to meet up with a friend you already know where they are. Instead, it's if you're in a coffee shop and you notice that your friend is in the book store 100 feet away, you can take advantage of that opportunity. As Sam says, it's surprising how there are typically close friends in your general vicinity that you wouldn't know were there otherwise. SMS can't replicate this behavior.
