I really don't understand the issue. But then today I received a press release in email saying that a lot of music stars, along with moveon.org, are making a stand in favor of net neutrality. How are they doing it? By posting messages on Twitter and Facebook.
Neither Facebook or Twitter allow peering. To get on their network you have to be in their network. It's fine to use these tools, I suppose -- I do -- but if you want to take a political stand in favor of an open and free Internet, do it on the open and free Interet. Please.
Create a blog, put it on your server, hook it up to the net through one of the companies you're protesting against (that's what's worth protesting, your limited choice), and speak your mind. Then, if you must, tweet links to those stories and share them on Facebook.
