Check out The Online Coalition which is an organization comprised of bloggers from both the left and the right. Federal Election Commission Commissioner Bradley Smith recently did an interview with CNET.com. In it he suggested that there would be a "coming crackdown" on internet bloggers' free speech.
Another great site is The Electronic Frontier Foundation. They publish A Legal Guide for Bloggers and advocate for internet free speech rights.
I believe the internet is essential to continued democracy in this country. Let's keep the internet free speech going!
