And that's ignoring that niche it filled where people were identified by emails, and the particular social rules of knowing that if you went online, it meant you wanted to spend a while talking to people and were available to do so. Discord is kind of similar in that last aspect, but it's enormously complex for the average user and intended for servers, not for 1 on 1 conversations with your contacts. I've always wanted to build a clone of Messenger just because of how much I miss it.
