(Notice each 'more' link shows how many replies you'll see if you follow it.)

Installation instructions:

- Install tampermonkey: https://chrome.google.com/webstore/detail/tampermonkey/dhdgffkkebhmkfjojejmpbldmpobfkfo?hl=en

- Go to hacker news

- Click the tampermonkey icon (upper right)

- Create new script

- Replace it with this entire gist

- Press Command-S to save. (Control-S, whatever. Make sure you actually save, otherwise it won't work.)

- You should now see how many comments are waiting for you at each 'more' link
