I blogged on net neutrality before, and so did a lot of other people.
(see e.g. Danny Weitzner, SaveTheInternet.com, etc.)
Since then, some telecommunications companies spent a lot of money
on public relations and TV ads, and the US House seems to have
wavered from the path of preserving net neutrality. There has been
some misinformation spread about. So here are some clarifications.

Mpegs to come)

Net neutrality is this:

If I pay to connect to the Net with
a certain quality of service, and you pay to connect with that
or greater quality of service, then we can communicate at that level.

Net Neutrality is NOT asking for the internet for free.

Net Neutrality is NOT saying that one shouldn't pay more money for high quality of service.
We always have, and we always will.

There have been suggestions that we don't need legislation because
we haven't had it. These are nonsense, because in fact we have had
net neutrality in the past -- it is only recently that real explicit
threats have occurred.

Control of information is hugely powerful.
In the US, the threat is that companies control what I can access for commercial reasons.
(In China, control is by the government for political reasons.)
There is a very strong short-term incentive for a company
to grab control of TV distribution over the Internet
even though it is against the long-term interests of the industry.

Yes, regulation to keep the Internet open is regulation.
And mostly, the Internet thrives on lack of regulation.
But some basic values have to be preserved.
For example, the market system depends on the rule that you can't photocopy money.
Democracy depends on freedom of speech.
Freedom of connection, with any application, to any party, is
the fundamental social basis of the Internet, and, now, the society based on it.

Let's see whether the United States is capable as acting according to its
important values, or whether it is, as so many people are saying,
run by the misguided short-term interested of large corporations.

I hope that Congress can protect net neutrality, so I can
continue to innovate in the internet space. I want to
see the explosion of innovations happening out there on the Web,
so diverse and so exciting, continue unabated.
