Regarding this SO question:
A user came along and removed the "jQuery" tag on the OP sometime after two jQuery dependent answers were posted.
Then others come along, myself included, and see answers pertaining to jQuery where they don't seem to have relevance to the question.
In my opinion...
2) The Responders should probably not rely on tags alone to know what kind of solution the OP is wanting. Perhaps comments should have been made asking the OP to clarify his use of the jQuery tag. Otherwise, maybe start their answers with, "Since you tagged your answer with X, here's an X solution..."
Are tags allowed to be used as an enhancement to the question* thereby the original tag in this example should not have been removed? Or should tags simply describe the question as posted**, where Responders should only read the question and not use the tags as additional guideline for their solutions? I'm heavily leaning towards the latter.
Yes, as per the FAQ thread, tags are supposed to be for categorizing the questions.
*"enhancement to the question" - Should the categorization be arbitrarily based on what kind of responses the OP wants?
**"describe the question as posted" - Should the categorization be based on the content of the question alone?
