Joshua Schachter, who in a past life founded the social-bookmarking service delicious and sold it to Yahoo, has released Human.io, the newest offering from his startup, Tasty Labs. Last year, Tasty Labs launched Jig.com, a "market place for things people need."
What is Human.io? To me it appears to be a micro-task platform that uses mobile devices as a way to distribute and aggregate tasks.
