We are working to improve the UX experience. Currently you should be able to open up the notifications area (global in the top right corner) and click on the comment notification, which will take you to message within the comment thread. You can also navigate to the comment through the email.

If this is not working as I described please let us know. I am currently working on some bug fixes related to all of this.

Also it should return integer, not string. And again it's too slow on big numbers, try to find another way:)

Don't use puts... Just return the number... When you use puts as the last line of your method, you end up returning nil.
