Summary of results

Mood by category

Data collected during the first month indicates that most feedback submitted by new registered editors is of the "happy" type (58.6%), followed by "confused" (30.9%) and "sad" (10.5%). New editors tend to submit "happy" mood earlier in their user experience than "sad" or "confused" mood.

Mood with comments/transactional mood

75% of Moodbar events submitted by users include a non-null text comment, with a higher proportion of comments submitted in the "confused" (84.2%) and "sad" (81.4%) categories. A relatively small proportion of Moodbar events (10-12%) were submitted while editing, suggesting that feedback is not immediately linked to the edit transaction.
