If you've read the front page recently, you're well aware that there's a large percentage of total crap on it. Indeed, more than a third of the questions posted in the last 60 days have been closed or deleted. I'm led to believe this is quite a high number among Stack Exchange sites.
This post is about one possible way to reduce the number of of poor quality questions:
Remove the ability of unregistered users to ask questions.
This has been done for some time on SO, Programmers and probably some other sites, with varying outcomes.
A look at our recent statistics shows that 57% of questions posted by unregistered users are "bad" questions. And our resident statistician informs us that making this change could reduce our bad question rate by up to 13%.
But shouldn't we make it as easy as we can to ask questions?
It should be easy to ask a question, but my feeling has been for some time that it is much too easy to ask a question here. We're not meant to be a site which will Google the answers for you or write your configuration files line-by-line or walk you through the finer points of plugging in a network cable.
Requiring registration may discourage poor quality drive-by questions from people who won't even return to improve their question or accept an answer. For those who do register, it gives them a moment in which they may hopefully begin to KEEP CALM and WRITE A BETTER QUESTION. Ideally.
Is this all you've got? This won't have much of an effect.
No, this won't have a large effect on the rate of poor quality questions. But every little bit helps, and I have other ideas which I'll also be proposing in the days ahead.
user9324901screams "I don't really give an ish about your site or your members, just fix my issue." While there may be benefit for future views and a possible accept, it carries the air of a perfunctory question, blasted out to multiple Q&A sites in hopes of an answer. It's human nature to feel more connected to a user here with a "real name" vs. machine generated anonymity.
