This is true, but it also could make you seem like you're fishing for commenters or reviewers, by cross-posting the same content to three different forums.
Well, technically, we're all fishing for commenters and reviews. We just all go about it differently. I want people to review and comment on my thread, but I lack any kind of gully to drag them to it or make it hard to miss. Some people will post the same story in different forums. Some people will post the same story in the same forum. Some will advertise their story in every single thread they post in.
Ironically enough, the deeper the degree of your advertisement, the more you turn people away from it. However, in the end, we all want the same thing.
