### I. Purpose of Subscription?
In the Web 2.0 era, one of the biggest changes in blogs (websites) is the application of RSS technology. On one hand, authors of blogs (websites) use RSS to generate continuously updated content or summaries of their articles, presenting them to visitors in the form of an RSS address, and allowing visitors to read these resources in ways that suit them best. On the other hand, visitors to blogs (websites) can aggregate various resources from multiple blogs (websites) they like through the RSS address (a process we call "subscription") and read their updated content uniformly, no longer needing to log in to blogs (websites) every day. Clearly, the application of RSS technology saves time for visitors and enhances the stickiness of blogs (websites).
