Looking at this answer (the link is now for 10K users, as the answer has been deleted), for example, I notice that it doesn't answer to the question because
- The fact somebody uses a word doesn't mean it's the correct word to use.
- The OP doesn't report to which English dialect he is referring; if there are any difference between American English and British English, for example, the answer doesn't evidence that.
Does saying "I have always used [X]" answer a question about which of two words to use?
In which cases is the answer really a comment, and in which cases does the answer really answer the question?
