Allow Yahoo commentators to access their comments. Changing that feature was a terrible, unpopular idea

It used to be that we could see our comments under each article, but now, I have to look around before I can both comment and read my replies.

Just give us an option to see if anyone has reacted to our comments. It is virtually impossible to find a specific comment on a story that has garnered a lot of attention. If you are going to allow comments at all, make them part of a larger dialogue.
