Reading/keeping track of replies to your comments

So I made this page that tells you if there's new replies to your comments and even allows you to read them conveniently.

http://verge.site44.com

(Clicking on the "x new!" button will load the replies automatically.)

Technically, it's all html/js so it's safe and you can save the page and run it locally.

Try it and tell me what you think.
