Today I was reminded that old online chats offered context awareness for the people online: you knew you won't be a bother to a friend who has a smiley flower as a status; and you knew you might not be getting a quick reply from someone who's Away.
Today I don't even know if my friends are online or not. The messenger apps make the assumption that everyone is online, and if not, they will receive a push notification, and will reply to you as soon as possible. But this assumption is barely true. I bet it makes lives harder, especially for ND people

@nina_kali_nina I wish I could remember my ICQ number!
