Here and at That Other Site there are some on-going topics. For example, there is always some of this meta-discussion going on, often completely offtopic. So if there was a kuro5hin story that was always there, all this discussion could be moved there, instead of the random stories that pop up. Other static topics may be on-going events that could last a few months and then end (like the ineffectual breakup of a software compay), etcetera. The problems that would need to be solved are how to deal with the continuous flow of new comments into these topics (sort them 25 most recent on first page, then a button for next 25?), and how to decide who gets to create topics (perhaps similar to the article posting thing, but where you can change your vote later once the topic has outlived its usefulness).
I've seen a number of instances where people would post something if there were some sort of sub-section for that sort of articles, allowing it to appear but not on the main page. For example, a "rant" section was recently requested. /. sort of has this but sort of doesn't. Once again, this would ideally be member controlled to fit in with the open and self-maintaining ideas of k5 which I think should be maintained, here and on other sites of this ilk.
Often a story would be good if it weren't for a couple of minor points. How can we fix little problems without scrapping the story and starting over again? Give the author the ability to change the post and members the ability to change their vote? Some way of posting a story as "in lieu of"? Or is posting an entire new story a sufficient solution? It seems to be at this volume, but how will that scale when we get more users and many more stories?
Or not ...
All in all, Scoop is a very slick design and handles everything quite well (though we haven't really seen how it scales yet, have we?), the authors should be proud. If any new features might be added to this (or anything else), one must always consider if they're fixing something that isn't broken. Also, if features aren't implemented with care, they could make things worse rather than better. That said, if new features are never considered, the possibility for an even better site disappears. My particular suggestions may not be of value, but I think there is room for improvement, although I'm not sure what form that would take.
