I like the new comment highlighting, but it should stick around for longer. If I refresh the page, it’s gone. Even worse, if I click on Replies, then comments are not highlighted anymore once I click on the whole thread.
It’s not really a “new” as it is “unread” marker. It assumes you’ve seen it when you load it.
Wouldn’t it be better if we changed it?
What would be the criteria for it to transition from “read” to “unread/new?”
The system should highlight comments that are newer than last-visited-time, but last-visited-time should only increment in 20-30 minute intervals. This is what reddit does, and it seems to work well. Actually reddit also provides a dropdown menu where you can chose which of these recorded last-visited-times to use, in case you don’t want to use the latest one, for example if you clicked in a thread by mistake while at work but still want to see newer comments than when you last read it in the morning.
