The use of censorware by repressive governments is now becoming a
legitimate policy matter. Conferences are being held, proposals are
being made, press articles are being written. And people want to know:
how can we make a difference in the fight against world censorship?

I don’t have a good answer. Non-governmental organisations, thinktanks,
academic departments and so on all have their own hierarchies and
barriers to entry.

Many years ago, when the internet was much
smaller, the corresponding reach of an individual aiming to be heard in
it was much larger. But the integration of the internet into society at

in terms of overall influence as they are in society at large. It’s not
that nobody at all had a voice, but that the standard institutional
power structures asserted themselves.

And blogs are no solution.
Contrary to blog evangelism, blogging can sometimes even be detrimental
in terms of building influence. That’s counterintuitive, since the very
rare person who achieves substantial influence via a blog is often
widely touted as a success story.
