The simple hack I use in my own extension to provide that feature on reddit without Gold just simply logs the timestamp of every visit of the thread in a cookie, and then allows to select "new comments since visit X", and then just computes the comment time back into a timestamp, compares, highlights.
If HN would provide the actual timestamp in ISO format, as reddit does it, we could've had that a lot simpler a lot earlier.
For other people's interest - there is a "Reddit New Comments Highlighter" chrome extension that does that for non-gold users.
I could've saved a day of work if I had known that before, lol.
Although my thing nowadays uses an XPosed module to integrate with Relay and uses a server, cause I wanted that to work.
