There have been many discussions on meta (here and here for example) about using the Ubuntu version tags (12.04 etc). Mostly, they support the position that these tags should be used when the version is somehow relevant to the question. If it is a general issue and the OP just happens to be using version X, then the question should not have the version tag. For example, a question like "How can I change the permissions of a file?" should not be tagged with a version since its answer will be applicable to any Ubuntu (or *nix for that matter).
Now, I don't want to start this whole debate again. We have already talked about this ad nauseum. What I want to point out is the following quote from the "on topic" section of the help center:
Ubuntu version you are using in the TAG, including any other Tags that can help on the question.
That means that the more conscientious new users, those who actually read the help center, are given the idea that all questions need a version tag. Whatever you position on version tags, I think we can all agree that not all questions need them. Yet, this is what we tell new users to do. This seems like shooting ourselves in the foot.
So, shouldn't that particular bullet point be removed?
