Vocal Nation is a personalized feed reader that we mentioned a few months back in our Mashable list featuring online political resources. As a dual-purposed site for aggregating news and discussing various topics, Vocal Nation is now launching the second version of its site, with a focus on its newly implemented voting system.

In an effort to differentiate itself from Digg, Digg clones and the Digg voting system all together, Vocal Nation's new feature helps set it apart in two primary ways: an automated submission process and a sliding scale used for voting. While the slider isn't as straight forward as a thumbs up/down approach to voting, it nevertheless aims to bring a more complex approach to community feedback.
