Doubt any of you still recall me however, I just wanted to lend my support to the "comments" option. I know back when I was still writing here, my largest concern was if anyone was actually reading what I wrote (for better or worse). I see this option not only helping authors communicate with others on story ideas, but also allow the community to possibly help new authors as well.
I believe the reason we are hearing such a large outcry from the "comments" gallery and not from the "tags" group is authors (who would have accounts on the plume) are desiring the comments. On the other hand, a feature like "tags" would be a favorite for readers, who would rather get to what their pleasures are and not have to sift through a thousand stories to find them.
Anyways, that's my two cents.
