  • 为什么这么多人不相信个人媒体，而要相信大众媒体？另外一个重要的原因就是对个体的潜意识排斥：个人怎么能成为媒体呢？个人成为媒体了，是不是有什么“特殊用心”呢？是不是为了欺骗我呢？这一系列问题的提出，其实是有原因的。这要追溯到90年代的疯狂传销所埋下的祸根。
  • 大多数人，仍然坚持相信机构媒体、机构内容。这些人，没有自己的观点，也不愿意相信其他个体的观点。只要他们不被机构媒体害得没饭吃，他们就不会有什么抱怨。

  • 优秀的设计往往源于巧妙的减法
  • 导航必须提供有意义的跳转链接； 导航必须要传达出各链接之间的重要级别和相互联系； 导航必须要传达出与用户当前所浏览页面的关系。
  • 一个良好的解决方案应该是用减法来提炼任务过程而不是用加法来增加用户的认知负担

  • 论上——再罗嗦一遍——理论上，原则都是对的，道理大家也明白，可实际设计过程是怎么样的呢？

    事实上，互联网媒体正在越来越精英化。从最早依靠转载起家，到过去的互联网媒体的初阶段原创化，紧接着的是现在，互联网媒体的细化竞争，也就是分领域专业化，结果是什么呢？

迷途不返◎笑骂江湖 » 关于草根与精英的随感随写 - 0 views

  • 我其实一直对“草根”这词很不感冒，这个称谓更象是媒体赋予的骗局。事实上，多数的“草根”仍是被忽视或仅仅被当作基数提及的，而以“草根”身份成名的作者，正逐渐演变为新的“精英”，甚至这些知名“草根”们都有成为“精英”的欲望

      Good point. 所謂的「草根」們，都有成為精英的渴望。真正的草根，可能不知道互聯網是什麼東西。
  • “草根”是媒体赋予那些未成名的作者的一个定义，但真正的“草根”其实是那些被当作基数的网民，我们当然不可能忽视“草根”群体的存在，我们只是不可避免地忽视了他们做为个体存在的意义。
  • 互联网是为人服务的，因此不要妄想互联网改变人性，事实上互联网放大了群体的人性特征，基数越大，金字塔的顶端越是高得结实。理论上说，任何一个领域都不存在直上直下的基数与顶点的形态，更不用说倒金字塔形态了，“草根”压倒“精英”这根本就是违背人性的伪命题。

  • 偷换概念好像也是刘韧先生文章的一大特点。至于“新闻借着互联网回到百姓手中”这话就更怪了，如果说互联网让老百姓更容易获得真实的新闻甚至参与提供真实的新闻，这倒可以理解，但“新闻回到老百姓手中”？这我实在看不懂。

Lorcan Dempsey's weblog: Recommendation and Ranganathan - 0 views

  • Now, typically library catalogs use traditional information retrieval techniques over professionally produced metadata. This is not a lot of data to play with! We have just begun to see interesting things being done with the other types of data as libraries explore the use of transactional data for recommendations and look to incorporate contributed data.
  • Google, Amazon and other sites license professionally produced metadata. But in different ways they also use the other types of data also.
  • Suggestion, or recommendation, is becoming increasingly a part of our everyday web experience,and improving the quality of suggestion has become an important goal for many services. Clearly, there are commercial interests riding on this.

  • "The 20th century was about sorting out supply," Potter says. "The 21st is going to be about sorting out demand." The Internet makes everything available, but mere availability is meaningless if the products remain unknown to potential buyers.
  • When I get good recommendations, I spend my time and money differently. Even better recommendations will dramatically increase the value of that time and money.
