Zistle
Zistle.com is a sports card community built around our collection management suite of tools in PHP and then Ruby on Rails. We own this website and continue to actively develop it. It was initially launched in early 2009 as a beta project to experiment with crowd-sourcing and data manipulation at large scale. It has since taken off in the sports card community and has received rave reviews from users both for its ease of use as well as its performance. It has quickly become the definitive online resource for sports cards collection management and is one of the largest databases of sports card images on the internet.
