I tried, really a good voting tool. But still not the one I asked for.
You see quora, zhihu, and some bugfix sites. People ask a question in the very first place and have many answers. People vote on the answers and then the most voted answer will be listed first as the best answer.
And this is a voting for the whole topic. Actually, I’m wondering why people want to vote for a whole topic?
And, I found it won’t move up or down the topics if such topic have more votes.
Actually, I think this is a better plugin
