Seriously, read this.

Without network neutrality, Tumblr could cut a deal with your ISP — let’s say it’s Comcast — and its blogs would load really quickly while that home server blog might take minutes to load pictures. It might not even load at all. You can see why people in the freedom-of-speech obsessed United States might not be happy with chucking network neutrality. It privileges some speech over others, based on financial resources.

And more:

This is the first step toward a world where corporate monopolies on content start affecting not just what you can see and read online — but also how you gain access to it. The signal will be out there, but your ISP just won’t deliver it to you.

An internet without network neutrality will look a lot like television does now. You’ll depend entirely on your cable company to get broadcasts, and they will only deliver their handpicked channels in their cable packages. There will probably be a little room for the web equivalent of public access television, but it will be so underfunded and slow to load that almost nobody will see it.

It used to be that when a show couldn’t make it on broadcast television, we would watch it online. That’s how amazing stuff like Dr. Horrible made it into the world. But without net neutrality, we lose that option too. If a company doesn’t have the money or legal acumen to get its content included in ISP packages, you will never see its programming. You’ll never have those shows; you’ll never have those apps; and you’ll never know what you’re missing.

Call your congresspeople. Make noise. This is a big deal.
