The "Balance Bar" is a easy to use browser extension programmed to allow any user to editorialize any web page anywhere on the Internet. Once you have an account (which is free) you can use the "Balance Bar" to literally insert your comments/article/rant directly onto whatever web page you would like to expound on. The "Balance Bar" was developed because of the increasing need to "balance" the one-sided and isolated world view that much of our media sources produce.

The current version of the tool bar is developed for the PC and Internet Explorer only. I am working on an extension for the firefox/mozilla browser but that is several months away. The source is available for anyone who'd like to help out.
