DayTipper – Read and Share Tips
http://www.daytipper.com/

Daytipper was established in 2005 by colleagues that share a common goal: develop a service that allows the global community to submit and share tips, information, advice, and ideas. Founded by experienced veterans of the Internet and publishing industries, their mission is two-fold: assemble a popular and useful collection of tips, and allow everyone to contribute.
