驾驭Web 2.0浪潮
一些在Web 2.0大伞下的应用已经非常流行了。2001年，20%的美国网络用户（即大约2,300万美国成年人）使用在线服务来处理或展示图片。2005年，网络用户已经增涨到1亿4500万，在线处理或展示图片的用户比例增加到34%，即4,900万用户。
然而，在过去的几年中，用来上传、分享以及现在对图片做tag的应用已经发生了相当大的变化。Hitwise的数据显示明确的Web 2.0社会化集成的图片服务的高速增长，如与传统的在线图片站点如Kodakgallery所表现的市场停滞不前相反，Photobucket表现出了强劲的增长速度。
- Web 2.0与下一代互联网没有任何联系；
- Web 2.0并不是一个运行于独立骨干上的全新的、得到改进提高的互联网络；
- 如果你听说过这个概念，并点头表示认可，没有关系，但是你并不十分清楚它真正的含义是什么。
