Thumb is based on the concept of crowd sourcing. Crowd sourcing is tapping the collective Intelligence which leverages the wisdom of the crowd to generate new ideas and to refine ideas that exist, as well as vote on the “best” idea.
Thumb uses personal crowdsourcing. For example, my daughter doesn’t know what to match with her new skinny jeans. She can upload a pic to Thumb and then use collective intelligence to source the best match.
It appears like even simple questions typically generate hundreds of thumbs up or thumbs down, plus comments, sometimes within minutes.
The site has very high engagement of its users with 4 hours a month of use by its members, which is second only to Facebook!
