Just a quick and dirty hack I did while learning Go and how to set up an EC2 server. A proof of concept for a feature I think it would be useful on HN.

It often happens that I read the whole thread of comments for a discussion, and get back to it at a later time to see the updates.

It's hard to see at a glance which comments are new and which ones I already read.

The app uses cookies to record the last time you accessed a discussion thread, and modify the html in order to highlight the new comments (the ones added since your last GET of the page).

Just access a discussion thread through the proxy site, and come back when new comments are added to see the effect.

(Obviously I don't have access to HN backend, so you can't do anything more than reading a thread).
