This is more of a rant then it is a question.
The website is too strict on what it wants as its topics right now. It is at a very early stage and you want activity on the site. If you close most of the topics, mark them as duplicated, make them community wiki, leave comments instead of answers people are going to turn away. That will just lead them to coming to the website for a question, getting their answer and leaving. It will not encourage participation.
As some of you may know, you guys are competing with another math forum (which is also in its early stages).
Also, its really annoying to see the first comment on a question as "community wiki?" or "this should be community wiki". Right I am aware it should be community wiki. I just posted the question 5 seconds ago, give me time to breath.
I personally think we should be more lenient (at least in this very early stage) to allow for more broader topics. It does not do any harm and just promotes the site. My background in math is not very strong.
