We talked about it briefly in chat about starting a Topic of the Week event, akin to what is done at Astronomy and Space SE. I had proposed something similar here previously based on what was done at other SE sites discussed therein.
So, how about we look at a just-for-fun Topic (or Tag) of the Week? Here's some of the things that would need to be decided/fleshed out:
How long does each topic run?
Well, the precedent is a week. But sometimes it takes longer to come up with really good questions or answers about highly technical aspects. Maybe two weeks would be better, but then we run the risk of getting tired of the topic in the middle. So I propose a week.
What's the point?
There are three goals this serves. First, it promotes the asking and answering of questions the community deems interesting. Tired of newtonian-mechanics? Suggest something else you are interested in and get some questions and answers!
Second, it could be used to attract higher-level participants. If there are things experienced members would like to focus on, decide and participate accordingly.
Third, it's something fun to do and will get many people outside of their comfort zones. I don't know anything about most of the tags here, but I would be encouraged to do some digging and ask a question about them if I knew it would get answered by people who know about it!
How are topics/tags chosen?
In the preceding month, a question will be posted here on meta to take nominations for the 4 topics of the next month. Each nomination should be it's own answer and ideally should contain at least one sample question already on the site pertaining to it. The 4 answers with the highest votes at the close of the voting period will be chosen -- let's say the voting period is 3 weeks. If topics should fit in a particular week of the next month, that should be noted; for instance, if a big announcement from CERN will be made in the first week of December, it might be good to put the particle-physics topic during that week or the week after.
What does the timeline look like? Assuming we get started soon:
- Nov 1 - Nov 23: Topic proposal and voting period for December's topics.
- Nov 23: December's topic proposal question locked.
- Nov 27: Topic schedule for December released
- Dec 1: First topic week begins
- Dec 1 - Dec 20: Topic proposal and voting period for January's topics.
and so on.
What constitutes a community decision?
Highest voted topics get chosen. Well, let's say the highest of the 0-or-greater votes. If all the topics are positive and there's a tie, the mods will split the tie up and feel free to nominate again for the next month. If all the topics are at 0 then there is no interest in continuing and we give up. If we can't get 4 positively voted topics, we give up. If all topics are negative, we give up.
In other words, we can only do what the cross-section of community here tells us to do.
What tags should be nominated?
First and foremost, tags that you find interesting. The second goal may be to propose tags in which there is relatively low participation as a means to promote questions and answers in that topic.
What tags should not be nominated?
Under no circumstances should a meta-type tag be nominated! So no homework, research-level, or popular-science. Whatever tag is nominated could have questions from all three of those categories asked during that time, so let's not limit the level of the question, just the scope.
I would avoid overly broad and overly specific tags as well. Something like newtonian-mechanics is very broad and there's already a lot of questions on it so it probably doesn't need to be made a topic (although this is a guideline, not a rule so it could be -- the community will decide whether to use it or not).
Why should I participate?
No seriously, why not? Do you know everything conceivable in your field? Do you know everything about every other field? Why not take the chance to read about something new or dig a little deeper into something old? Why not use the site as it's intended -- to pose questions you would like answered, or to answer questions you have the knowledge to answer?
