这个小组发现在Menéame网站上，讨论树比较纤细--用户倾向于直接回复主题帖而不在跟帖中发言。
The team found that in Menéame, the discussion tree is skinny—users tend to post directly in response to the news story and not to talk amongst themselves.
下一代码段在提示框中显示每个回复文档的主题，以便于用户选择任何组合。
This next code snippet displays the subject of each response document in a prompt box for the user to select any combination.
举个例子，如果你给我发送一封邮件，邀请我在一个会议上发言，我问发言的主题是什么，你可能只回复我这个主题，剪去了所有关于这个会议的细节。
For example, if you send me an invitation to speak at a conference and I ask what the topic is, you might reply with just the topic, snipping out all the details of the conference.
