Does the reflection on the tag cloud confirm the contextual factors suggested by the framework?

Evaluation• Design research study– Qualitative method

• Delicious users from several communities

• Voluntary participation• No participant was

aware of the framework

• Reflective notes– Analysis: model driven labelling

Results

• 76 registered– Official tag cloud is rarely used

• 9 note taking participants

• 35 reflection notes over a 9 weeks period
