Whenever I'm going to post something, I end up asking a lot of questions because I want to resolve as many doubts as I can..I've already canceled three/four questions because of this and I'm about to cancel one more.I wanted to ask more questions, but my post will be closed, so that's all.
We really like lots of questions! Stack Exchange only allows you to ask one question per post. All you have to do is ask a well focused question and we can answer it. You may ask as many questions as you need to ask in order to address the problem. This makes the process easier for all of us.
Nós realmente gostamos de muitas perguntas! O Stack Exchange permite que você faça apenas uma pergunta por postagem. Tudo o que você precisa fazer é fazer uma pergunta bem direcionada e nós podemos respondê-la. Você pode fazer quantas perguntas precisar para resolver o problema. Isso torna o processo mais fácil para todos nós.
I think you have already been told to give a good read at our help center.
If you go there you will find a section called "What questions should I avoid asking?" which precisely answer your question here:
You should only ask practical, answerable questions based on actual problems that you face. Chatty, open-ended questions diminish the usefulness of our site and push other questions off the front page.
Your questions should be reasonably scoped. If you can imagine an entire book that answers your question, you’re asking too much.
Asking more questions in a single post leads to getting overlapping threads in the answers, making it more difficult if not impossible to pick a "best" one.
The limit of one question per post is a design decision that is at the core of the Stack Overflow model.
When you have multiple questions in one post it makes it harder to identify and highlight the good answers. What if answer A does a fantastic job with question 1 and doesn't even attempt to answer question 2? Do you allow it because it is excellent at Q1 or delete it for not answering Q2. Since stack overflow was built around the idea of collecting good answers they decided to make it simpler for the answerers by restricting posts to 1 and only 1 question.
