user24: We've recently had a slight drop in traffic, and while that in and of itself isn't too worrying for a number of reasons, it does indicate that we should probably at least look at whether there's anything we're not doing right. 
If we want to get traffic, the most obvious series to target are those that are currently airing. But at the moment, we don't even have tags for a very large number of currently airing series. Not having a tag means that new users aren't likely to bring their questions to us, unless they happen to be aware of retag or use something else that doesn't quite fit. So it makes sense to prioritize creating tags for these series.
Of course, the way tags are created on Stack Exchange sites is by users asking questions. We can't create tags if no one is asking a question, and even if we did the tags would be removed if they weren't being used on any questions. So what this really means is that we need people to volunteer to ask a question about these series to get the tags into the system.
Given that Fall 2014 season is just beginning, now seems like a good time to do this. The purpose of this post is to keep track of what series are airing this season, what tags already exist, and which series still need tags, and to coordinate efforts to create these.
If you're willing to contribute by asking a (good) question about one of these series, feel free to leave a comment under the answer. Once you do (preferably as soon as possible), edit the relevant line on the answer to point to the tag page. The hope is that by doing this, we can get to something like 50% coverage of all airing anime, which would mean most popular things are covered. 
Of course, this is completely optional, but if you do notice a series that you're watching is listed as no tag, at least consider whether you can come up with a good question about it.
