I'm starting to see occasional collapsed comments when I open threads. The first time I saw one, I thought I'd accidentally collapsed the comment myself, but this one was definitely already collapsed when I opened the thread.
Is this related to the "tagging" system that Deimos discussed the other day? At the time, he said that "tags" wouldn't have any effect. Are these effects now working? What are the effects? Also, there was no actual decision about what the different tags would be, and what they would mean. As I said in that thread, I decided not to use these tags until: a) they were agreed and defined; b) they actually did something. I thought they were just placeholders for now. I'm confused.
Or is there some other feature operating here? For example, people keep talking about "whisper" comments, and I'm not sure if they're just fantasising about a feature they would like, or if it's something that's actually planned. Are these those "whisper" comments?
