This question already has an answer here:
- We are getting lots of problems with the quality of questions from new users.
- The unwillingness to register shows a lack of commitment to the site and hence is a good indication that the person will not spend the time learning how to post good questions.
- We are getting a lot more questions than we need, it could be claimed that Stack Overflow is becoming less useful due to the volume of questions.
Should unregistered users only be allowed to answer questions and not post questions?
In the old days Stack Overflow benefited from lots of questions being asked, so it made sense to make it easy for anyone to ask questions, I no longer see the bandit from increasing the already great volume of questions.
(The site I use other the Stack Overflow, don’t seem to be getter the same problems with the volume of poor questions.)
The way I think of it is when a nation is first formed, anyone including convicts are let in, but once something worthwhile has been built, a system is put in place to only allow in people that are a net benefit to the current residence. I am now thinking that a lot of the new unregister users that are asking questions will never become a net benefit to the current committed users.
