This document summarizes a research study on the relationship between trust and attitudes towards sharing in distributed personal learning environments. The study surveyed 32 students to understand their general trust levels online, attitudes towards sharing learning resources publicly, and preferences for features in blog-based learning tools. The results showed that while most students were open to public sharing, they also wanted control over privacy settings for different groups. The researchers concluded PLEs should support evaluating relationships and setting varied sharing levels for ad-hoc groups.
