Comment Swap as Critique Swap?
After reading all the comments on this thread, maybe it's not two features that are needed. I think with the comment swap right now some people take it just like it reads; a comment on anything related to the story that they received, and they wouldn't be wrong on that because after all a comment is a comment no matter what you put. A comment generally seen is something like:
"Wow. This was just amazing. I'm so in love with your writing. The characters [insert names] are so cute. The layout... I can't even. I'm so excited for more. Please update. I've subscribed." Which are completely fine with me if you happened to find my story not through comment swap. But for the majority of us it isn't about watching the comment number go up, it's about receiving feedback (and maybe a little complement at the end to make us feel good about the story) that we generally don't get through regular means.
I believe the comment swap feature should be more feedback / critique based since this is a writing community and generally that's why people post their work on such sites- to get out there and see what the reaction is. Maybe by having a name such as
Critique Swap more people would realize it's not just about a vague comment but actually about taking the time to read the story and find things that could use improvement.
If that was to happened I think the character count should not change because by people realizing it is a critique comment they will exceed that limit. Even if they just meet that requirement at least they would be able to give feedback on something, which is better then what seems to be happening to some of you now. If they did leave a comment such as the one above, one can always report them. I think by reporting a comment and having your story thrown back into the mix for a replacement comment is a really good idea. It keeps everything fair for everyone.
Also, even if there was a second comment swap feature for feedback what stops those from moving over to this one? Sure you can report them but right now you can do the same thing. It won't stop the vague comments from appearing. There will always be people who will go over to the second comment feature and not leave the comment you were hoping for while you left a great critique for someone else. Having two different comment swap features just doesn't seem like it would solve the issues.
To me making the comment swap a critique swap is a better way to show people that they should actually leave a comment about their thoughts and opinions on what could be improved with the story.
[Hopefully my rambling makes sense to someone other than me.]
