Updating a thread with new posts is the most beneficial method of adding new information at this time. But it seems like it might be a good idea to figure a method of rewarding users who maintain and update an existing post. This seems like a time consuming task and one that greatly benefits the community. Rather than having information spread out in multiple posts (which is what the system seems to be trending towards), I think we should develop a method of rewarding those who update and curate posts. Maybe this has already been addressed, or is already included in the algorithm, but I couldn't find any reference..
