　　The communal online encyclopedia will probably never be perfect, but that's a small price to pay for what it does offer. The criticisms in the reading are largely the result of prejudice against and ignorance about how far online encyclopedias have come.
　　尽管在线互动百科永远都不会达到完美，但是总体看还是瑕不掩瑜的。阅读部分的批评更多是来自于偏见和对于在线百科发展进程的忽略。

　　First, errors. It's hardly a fair criticism that encyclopedias online have errors. Traditional encyclopedias have never been close to perfectly accurate. If you are looking for a really comprehensive reference work without any mistakes, you are not going to find it, on or off line. The real point is that it's easy for errors in factual material to be corrected in an online encyclopedia. But with the printed and bound encyclopedia, the errors remain for decades.
　　首先，关于错误。对于在线百科有错误的这种批评是很难令人信服的。传统的百科全书也很难做到完全精确。如果你渴望一个完全没有错误的综合参考书，你是不会找到的，无论是线上还是线下。而且事实上，在线百科上的事实性错误时很容易纠正的，而那些纸质的百科全书上的错误，确实数十年难有机会改正。

　　Second, hacking. Online encyclopedias have recognized the importance of protecting their articles from malicious hackers. One strategy they started using is to put the crucial facts in the articles that nobody disputes in a read-only format, which is a format that no one can make changes to. That way you are making sure that the crucial facts in the articles are reliable. Another strategy that's being used is to have special editors whose job is to monitor all changes made to the articles and eliminate those changes that are clearly malicious.
　　第二，黑客篡改。在线百科意识到了保护条目不受黑客恶意篡改的重要性了。他们采取的策略之一是对于无争议的关键事实条目设置为只读模式，这样就没有人可以修改了。这样可以保证你相信条目里的关键事实是可以信赖的。另一个策略师设置专门的编辑来审查对于条目的修改，并删除那些恶意篡改的内容。

　　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。
