Websites for crowdsourcing cultural heritage support participation by displaying project progress.
Explanation/examples: Statistics and progress bars are commonly used to display evidence of user contributions in relation to the project goal. When the rate of participation is low, acknowledging each new volunteer or contribution may be a more favourable signal of progress than showing the number or percentage of assets processed.
Benefits: Evidence of activity and progress contributes to an expectation of project success, which encourages new visitors to contribute. Displaying project progress also contributes to a sense of achievement, and encourages users to contribute more.
