這是條非常明顯的經驗定律：如果有100個人在線，只有一個人會創造內容，10個人會與之產生互動（回覆或者改進），其它的89個人只是瀏覽。這點很明顯地體現在YouTube上，這是一個只用了18個月就從零發展到佔據60％的在線視頻瀏覽量的業績。
這些數字是有啓迪作用的：每天都有一億的下載量和六萬五千的上傳量—— 如Antony Mayfield（http://open.typepad.com/open）指出的，平均一個上傳量對應1538個下載量——每月兩千萬的固定用戶。
那些“消費者創造內容”的網站的內容創造者在用戶中的比率只有0.5％，當然這只是初期。不是每個人都知道 youtube（YouTube也的確讓下載比上傳容易，因爲任何一個網站都可以放置youtube的下載鏈接）
考慮一下來自其它社區內容項目的數據，例如維基：50％的維基文章編輯是由0.7％的用戶完成的，超過70％的文章是由1.8％的用戶寫的，來自“消費者禮堂”博客(http://customerevangelists.typepad.com/blog/)
早期來自論壇網站的數據表明80％的內容是由20％的用戶創造的，但是隨着數據的增長表明了web2.0時代的羣組（論壇）是如何運作的。例如，一個要求用戶互動與用戶創造內容的網站就會發現十個中有九個用戶只是瀏覽而已。
雅虎的Bradley Horowitz也說雅虎的用戶也是如此。在雅虎社區，（討論區）“用戶的1％會建立一個羣組，10％的用戶比較活躍會發表內容（包括回帖與發帖）所有的人都會從以上人羣中獲利”這是他在二月份寫在他的博客上的（www.elatable.com/blog/?p=5）
結論是什麼呢？就是不要期望太多人在線。當然，to echo Field of Dream，如果是你建設網站內容的，自然會有人來看。在現實中，最大的困難是，怎麼樣找到那些創造內容的呢？

What is the 1% rule?

It's an emerging rule of thumb that suggests that if you get a group of 100 people online then one will create content, 10 will "interact" with it (commenting or offering improvements) and the other 89 will just view it.It's a meme that emerges strongly in statistics from YouTube, which in just 18 months has gone from zero to 60% of all online video viewing.
The numbers are revealing: each day there are 100 million downloads and 65,000 uploads - which as Antony Mayfield (at http://open.typepad.com/open) points out, is 1,538 downloads per upload - and 20m unique users per month.
That puts the "creator to consumer" ratio at just 0.5%, but it's early days yet; not everyone has discovered YouTube (and it does make downloading much easier than uploading, because any web page can host a YouTube link).
Consider, too, some statistics from that other community content generation project, Wikipedia: 50% of all Wikipedia article edits are done by 0.7% of users, and more than 70% of all articles have been written by just 1.8% of all users, according to the Church of the Customer blog (http://customerevangelists.typepad.com/blog/).
Earlier metrics garnered from community sites suggested that about 80% of content was produced by 20% of the users, but the growing number of data points is creating a clearer picture of how Web 2.0 groups need to think. For instance, a site that demands too much interaction and content generation from users will see nine out of 10 people just pass by.
Bradley Horowitz of Yahoo points out that much the same applies at Yahoo: in Yahoo Groups, the discussion lists, "1% of the user population might start a group; 10% of the user population might participate actively, and actually author content, whether starting a thread or responding to a thread-in-progress; 100% of the user population benefits from the activities of the above groups," he noted on his blog (www.elatable.com/blog/?p=5) in February.
So what's the conclusion? Only that you shouldn't expect too much online. Certainly, to echo Field of Dreams, if you build it, they will come. The trouble, as in real life, is finding the builders.
