When posting a chapter in someone's interactive, you must ask yourself one question -
If I was adding this as a stand-alone item to my profile, would I want this to be used as an example of my writing skills?
Now, if you're just making an "Other" option, I understand keeping it short. However, I just recently got something that 1, had terrible grammar, and 2, could have possibly changed the rating of my item from a 13+ rating to an 18+ one (over on WdC). Overall, it was a short and ugly mess - I deleted it.
Please, have a sense of pride in what you write. I mean, if a professional reviewer from a well-known publisher came across your addition, it might pay to leave them a good impression of your skills.
