Usually when a new feature is added to the network, an announcement post is created and users are urged to reply to the announcement with any bug reports or possible enhancement requests.
However, I have noticed that after a while activity on the original post goes down, and I'm not sure if I should still reply to the original or create a new post. Is there some time after the original announcement when posting a new question is acceptable? Perhaps 6 - 8 weeks? On the other hand, maybe the announcement post can be closed to signal that separate posts are preferred.
