Google Reader is more suitable for users who have been online for a longer time and subscribe to a larger number of feeds. These users already have a fixed circle of friends, with less desire to make new connections, and simply hope to read as many articles as possible through their reader as quickly as they can. On the other hand, ZhuaXia (Grab虾) is more appropriate for beginner users who are just starting to get familiar with RSS. Features like the channel directory and popular article rankings can help them quickly get up to speed. Additionally, its powerful social networking functionality allows users to integrate into circles of interest more rapidly.
