People like to maintain control over their own time and attention; I totally get it. But you're right, I'm also surprised at the extremes to which people are taking it, going so far as to assume that ephemerality and confidentiality mean the conversation is somehow immoral or illegal. That's the kind of argument law enforcement makes against the use of encryption. It's an interesting double standard on HN. I work infosec. My frame of reference is different from many here. But there are many times where I: • want to ensure a synchronous conversation about an urgent matter, and • don't want someone forwarding a "quick blurb" ("Hey, eganist here. Got an urgent moment to talk about something unusual we're seeing with web service X?") and spreading workplace gossip about a security anomaly when the anomaly itself is still being investigated to determine whether it's an incident.
