(Totally unrelated, sorry, but about a month ago you and I had a brief exchange about the placebo effect.[1] I got distracted and missed your last reply and never responded. Sorry about that. It's too late to reply on the original thread, and I don't want to hijack this one, but while looking for an old comment I saw your reply and felt compelled to mention it to you. It was a good exchange IMO and I didn't mean to "ghost" on it.)
I appreciate the apology, but I don't feel ghosting on an online conversation should require an apology.
People have other lives, most often online discussions go way past their due date (I actually like the fact that HN doesn't give you a notification when somebody replies to your comment).
It was a good discussion though, the placebo effect is fascinating.
It's one thing not to trust Signal. It's another to recommend alternatives that are far worse.
