I would like a reply to comment feature to SO, so when someone replies to one of your comments, it will be shown on the summary page.
The reasons are:
- important information or comments may be lost if you don't manually check all the threads you've commented to.
- there's almost no way to see the newest replies to old comments, especially if you ask something in the comments.
- Comments are usually the way someone notifies you of things that have changed, sometimes those replies are directed at comments not at answers, and comments are frequently used to complete existing answers without creating new ones.
