[Riccardo Mori has a great post talking about App.net and the differences between App.net and Twitter. Mori has this really great statement](http://morrick.me/archives/6056):
>So, when someone starts interacting with you out of the blue, you don’t tend to think *Who the hell are you?* (as it may happen on Twitter). Instead, you feel like you just moved out of the big city, to a smaller town, and you’re surrounded by friendly neighbours who have come here for the same reasons: to escape the urban alienation, so to speak.
I like the analogy between big city and small town. It fits for me because while people are still strangers, strangers in a small town are more aligned with your beliefs and your life than the typical stranger in a big city.
Mori’s post is a great look at why App.net is not the same as Twitter.
