If the tag would be used to mean that the question is asked because of something related to work, then the tag is a meta tag, as it doesn't describe anything about the topic of the question; it describes the reason why you are asking.
As long as the questions are asked because of actual problems, the exact reason for which you are asking the question doesn't matter. If you are going to ask a question just out of curiosity, then you should not ask it. This is valid in any SE site, as the FAQ of any SE site contains the following paragraph:
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.
If your motivation for asking the question is "I would like to participate in a discussion about […]", then you should not be asking here. However, if your motivation is "I would like others to explain […] to me", then you are probably OK. (Discussions are of course welcome in our real time web chat.)
