Thumb is about Personal crowdsourcing – Say you have no idea what shirt to match with your new jeans. Snap a photo, upload to Thumb and crowdsource the decision. Simple questions typically generate hundreds of thumbs up or thumbs down, plus comments, from the network’s very active user base, sometimes within minutes. Appealing to the twin social impulses of vanity and voyeurism, Thumb generates serious engagement among users (reported to be around four hours a month, second only to Facebook among established networks) and seems poised for growth in 2013.
In fact, as they define themselves, Thumb is about receiving instant opinions from Real People!
