For some reason, when I messaged someone on Facebook Messenger, it always felt to me more like I was bothering them, than when I used AIM/ICQ in the past. So I felt it was never really used in the same way. So I think this app is an attempt to make it a bit more casual, less formal.

D'you think this could be — at least in part — because Facebook is an always-on environment for a lot of people? They're not explicitly on to chat, so there's more of an unstated barrier to beginning a conversation.
