  Users' persistent social media contents like posts on Facebook Timeline are
presented as an "exhibition" about the person to others, and managing these
exhibitional contents for impression management needs intentional and manual
efforts. To raise awareness of and facilitate impression management around past
contents, we developed a prototype called PersonalityInsight. The system
employs computational psycho-linguistic analysis to help users visualize the
way their past text posts might convey impressions of their personality and
allowed users to modify their posts based on these visualizations. We conducted
a user study to evaluate the design; users overall found that such a tool
raised awareness of the fact and the ways personality might be conveyed through
their past content as one aspect of impression management, but that it needs
design improvement to offer action-able suggestions for content modification,
as well as careful thinking about impression management as one of many values
people have about their digital past.
