The first thing you should always do if you are confused about what's happening on a Stack Exchange site is to check the FAQ. From our FAQ (emphasis mine):
Programmers - Stack Exchange is for expert programmers who are interested in subjective discussions on software development.
Subjective does not mean "anything goes". Please keep it professional at all times. If this is a question you'd be uncomfortable discussing with your colleagues in a work environment, it's probably not appropriate here, either.
All subjective questions are expected to be constructive. How do we define that? Constructive subjective questions …
- inspire answers that explain “why” and “how”.
- tend to have long, not short, answers.
- have a constructive, fair, and impartial tone.
- invite sharing experiences over opinions.
- insist that opinion be backed up with facts and references.
- are more than just mindless social fun.
Questions that do not meet enough of these six guidelines will be closed as "not constructive." Please see the Good Subjective, Bad Subjective blog post for more details and examples.
After that, you should check the tags colored red on the meta-discussion site. If you did, you would've found this question:
Questions are being closed in accordance with the guidelines for this site. If you're confused because this is vastly different from the Area 51 proposal which has a lot of fluff questions, this redefinition was discussed on Meta.StackOverflow.com:
And discussed on this meta-discussion site:
I'm sorry you missed all of the discussion we had about the definition of the site, but the decision has already been made to redefine the site as it currently is in the FAQ, and the time for discussion is over.
If Programmers.SE no longer appeals to you or your question does not fit within the guidelines of this site, you might want to try to find a different site, like Yahoo! Answers or Quora.
