Information radiators in workplace environments display content from enterprise systems in semi-public spaces to support serendipitous discovery. However, display blindness can limit user engagement with such devices. This paper investigates how different content types influence engagement with an established workplace information radiator application, the CommunityMirrors. Three content types are distinguished: People, Organizational Units (Org Units), and Artifacts. A quantitative analysis of interaction logs was conducted over three months before, during, and after a lightweight two-step intervention consisting of a display-based poster prompting profile updates and a follow-up email to employees, thereby highlighting the People items. Results show that the People items exhibited the highest baseline interaction rates but did not sustain increased engagement following the intervention. In contrast, Org Unit and Artifact items demonstrated increases in the interaction rates over time. These findings reveal that engagement trajectories differ by content type and that interventions may redistribute attention across content types rather than amplify attention to the targeted content. Consequently, content managers and researchers can design engagement strategies for semi-public information radiators more precisely.     «
