Our aggressiveness in question-closing is well-placed.
First of all, let me point you to the Red Ink Initiative, which goes over the rationale for our current "aggressive-closing" approach in great detail. Here's the money quote, as far as I'm concerned:
StackExchange sites are designed to succeed where others fail by cutting out unhelpful noise.
And, similarly, the Area 51 FAQ:
The questions on your site say a lot about the community. To attract experts, you need a site where people are asking very interesting and challenging questions, not the basic questions found on every other Q&A site. Your goal is to make it clear that this is a professional site.
This means we simply cannot tolerate low-quality questions. A site full of low-quality questions will attract people asking more low-quality questions, and will keep away people who might have higher-quality contributions to offer.
Currently, the main page looks perhaps worse than usual, because Neil and I are going through all the critique questions as per our recent policy change. This unavoidably requires bumping up old material - including existing closed questions, and old questions that warrant closing. So you're seeing us at a low point - but that low point is well-justified.
We can't let up now
I am going to be as clear on this point as I possibly can: If Writers.SE slips too far down, it will be closed down. That's how StackExchange works, as we saw with sister-site Lit.SE and several others.
I'm not talking about our Area 51 stats - those are an indicator, but far from comprehensive. We're not doing too bad - but we've been "not doing too bad" for quite a while, and the crucial element to beta survival is growth. Writers.SE currently has a slew of major challenges to face - including site definition issues, a small number of regular contributors, the subjectivity challenge, and others - which I'd be happy to discuss separately, on Meta or in chat. I discussed this a bit more pretty recently, on What will become of this site? - take a look.
The point is, you're suggesting we basically say, "Well, we'll settle for whatever questions we get." If we do that, I can pretty much guarantee that this site's days are numbered. And for good reason, IMHO.
