I asked a question but it got closed before I got any answers. Stack Overflow says it is a Q&A site for all. I couldn't tell from the FAQ why it was closed, so can anyone explain what happened?
I was expecting this to be a language issue but I didn't really have any problems understanding your questions. It's just that they're very basic and rather open-ended. When combined with very short questions with grammatical problems people are inclined to vote down and close rather than spend time improving them.
I was torn on your Joda time vs java.util.Date question because it's a fairly narrowly tailored A vs B question and I think there could be useful answers. There's also a related question that might be helpful.
Also, when you changed it to
it wasn't really an improvement because we can't tell what that means. We'd have to know which programs in order to answer that in a meaningful way.
IMO I have seen many questions (Inluding my own) closed like yours.
The reason is for the use of questions like:
That is more for CodeReview, where as you'd expect questions like I am using this, but it won't work etc..
The question you asked would most likely solicit debate, and for some was vague, those were the grounds that IMO the question was closed.
Another good sign if your question will be closed is how long is the question?
Very rare a good question is 2-3 lines.
IMO the question was closed incorrectly as closed as not a real question and should have been closed as Not constructive (as it would solicit debate, you will only be getting opinions on which API is better not cold facts)

Look around the site at other questions that are asked. Are they short, one-liners like yours? Or perhaps you see lots of detail, some code? Did those questions make full usage of the textarea, or did they leave a lot of empty space?
I suspect that much of what you asked could probably be found on Google? Did you do a search before asking "What is Joda time?"
I just did a quick Google search and came up with lots of information about Joda time. Please see this Google search.
Now, let's assume you did actually search. Did you explain in the question what it was about those other answers on Google that didn't already answer your question? Did you describe in greater detail what the exact problem was you were facing, with code examples, error messages, what you've tried?
It seems like your question was closed because it's just too basic, and on Stack Overflow, we're looking for questions that haven't already been answered on every corner of the Internet.
With that said, consider editing your question. Closure is by no means permanent, and if you improve your question, it can be reopened by the community. So, tell us what it is that you don't understand. Give us the details so that we don't have to try and dig them out of you. :) If you do these things, you may find that you also get much better answers to your problems, and many more upvotes. Good luck!
