In the faq of meta sites you can read something like the following:
Voting here works a bit differently from other Stack Exchange sites. On Meta Stack Overflow, voting is used to express agreement or disagreement, not to point out a lack of quality or helpfulness. Please don't be concerned if you receive downvotes – members of the community may simply disagree with your bug, feature request, support issue, or the nature of the discussion.
My question is: If votes works differently on meta sites how does that of accepting answers work?
Take for instance a question on a meta site that is meant for the community to discuss some issue. What does it mean if the question is accepted? Accepting an answer is up to the author of the question so it cannot be a sign of what answer the community concludes from the discussion. It could mean that the discussion is over but that should be up to the community and not the author of the question. Is it so that accepting an answer for a discussion question on a meta site does not have a particular function?
