If you are referring to mine, I now understand what you mean. My first post has a list of plots and claims to have ten posts (which are all on the first page. I guess you can't win them all. You're the first to bring this up to me.I agree that this is often the case, but main the reason that I started the question was that I happened across a request thread in which the subsequent posts are no mere bumps but contain actual content that supersedes the first one, and sticking the first post makes it confusing.
It would be nice to allow the thread creator to override the stickiness, like in other sections.
