I am referring to Qual è una buona traduzione per Buzzword? to ask about a very general issue: the fact that here in ISE (but not only) comments are used to give answers.
Users who are new and don't have enough reputation to comment on questions asked by other users tys to reply with an answer. And the same users who hide behind the comments punish the answers with a down-vote. I don't understand this practice, but it seems to move away new people (or at least myself) from an active participation. In the specific I ask the person who down-voted my answer, why, and what was his contribution to the topic.
