Third, what's worth knowing about? The problem for traditional encyclopedias is that they have limited space, so they have to decide what's important and what's not. And in practice, the judgments of the group of academics that make these decisions don't reflect the great range of interest that people really have. But space is definitely not an issue for online encyclopedias. The academic articles are still represented in online encyclopedias, but there can be a great variety of articles and topics that accurately reflect the great diversity of users' interests. The diversity of use in topics that online encyclopedias offer is one of their strongest advantages.
第三，关于内容价值。传统百科全书由于受到空间的局限不得不决定哪些事重要的，哪些是次要的。然而，在实践中，是由学术团队的判断来决定的。这导致百科全书不能全部反应读者的兴趣和需求。但是对于在线百科来说，空间就不是问题。学术类条目在百科中存在的同时，还有很多种类的条目和内容用来满足用户多样性的偏好。在线百科在内容上的多样性是他们最大的优点。
