I have discussed this issue with some product people around me, and the feedback received so far is summarized as follows:
First of all, from the perspective of user experience.
1. Perception: Avatars occupy more screens than words and are at a disadvantage in showing more dynamic information;
2. Cognition: Avatars are not as easy to identify as words, and sometimes you don't know who is who when you look at them;
3. Action: The avatar is in the form of a picture, and the nickname is in the form of a text. Text is equivalent to a picture, which consumes less traffic and loads faster.
Second, from the usage scenario:
1. The praise of the circle of friends is more for friends, mainly to guide users to pay attention to the role of information. Use the path to directly display the likes of users when they brush their circle of friends. If a message is praised by many acquaintances, the reading value of this message will be highlighted and worth reading; In this case, nicknames (irregular information) are easier for users to generate visual information that many people like than headshots (regular information), and nicknames can better reflect which acquaintances like them (nicknames are easier to identify than headshots).
2. The likes in the photo album are more for yourself, mainly to help users review the role of statistical interaction. The usage path is: "Click photo album-click information-view information summary (content, number of comments, number of likes)-view detailed information content". Through the previous path, users already know how many people like and comment, and pay more attention to the content of comments when going to the details page, because there is a dynamic message (little red dot) to remind users that users already know who clicked on the comments. At this time, the regular avatar shows like, which will not interfere with the user's reading of the comments below, and will also make it easier for the user to identify how many people click like.
