Wow, thanks!

You've definitely given me some awesome ideas with this. My implementation is likely to be slightly different, but your links are an awesome start and will definitely come in handy.

I'll likely take a while to get to actually implementing my idea (>.>), but I think it'd be cool to share my implementation when I (finally) finish it. How best can I get back to you in perhaps a month or two?

Sure, contact me at [e-mail] (that email goes per default to my spam folder, if you send me an email today I’ll whitelist your address).

And the implementation is very simple: I just store every timestamp when you visit a thread (unless you visited it in the last 5 minutes already), and then just display those in a list.

Highlighting then all comments that were created after that timestamp is pretty simple.
