Try OpenSTV Online

Tim Fletcher has created an easy-to-use online Google app called Instant STV. With his app you specify a ballot file, select one of three methods (ERS97, Meek, and Warren), and request output in text or HTML. His app allows you to try OpenSTV before installing it on your computer.

The desktop version of OpenSTV has additional features that are not supported in Tim's app, such as numerous additional counting methods and the ability to create and edit ballot files.

Cornell Chronicle Article Cites Benefits of OpenSTV

Cornell University (my alma mater times two) recently used OpenSTV to count the votes for its election of the student member of its Board of Trustees. Cornell previously used an outside vendor to collect and count the votes. Now, Cornell uses its own system to collect the votes and uses OpenSTV to do the counting.

The Cornell Chronicle posted an article about the election and touting the benefits of OpenSTV:
