I asked a meta question a while back which was closed as a duplicate. I notice now that the original question is also closed.
Is it the case that once a question has been asked and a verdict reached that further discussion is no longer permitted? It strikes me a bit odd that because I missed out on the original question I now have no way of offering an opinion.
I can understand the reasons for closing exact duplicates (if it's a simple question/answer) but beyond that I can't understand why meta questions should ever be closed. My understanding is that the whole point of meta is for discussing ideas to improve how things work, and a good degree of that would be re-discussing old topics.
