Cory Doctorow's column in the Guardian about tech-politics and the importance of outreach by the tech community can be found here. Cory makes the point that ensuring your rights through technical skills is great, but not much help to society if the tech is too difficult for most people to use. Outreach activities and the hard work of polishing technical tools for non-techie use are of vital importance.
However, I do think that one important aspect was missing from Cory's argument, so my additional comment on another vital aspect of current tech/internet politics is below:
As nerd-politics is a subset of 'normal' politics, it's not just the nerd-part we need to worry about. The political system itself needs to function - at least some of the time - to get anywhere. If a country has a political system that retains the rituals of a democracy but no longer actually functions as such, then no amount of good nerd-politics (or politics of any other kind) will fix anything. Especially if such a fix threatens established and well-funded business interests.
It is perhaps no coincidence that all the bad tech-policy examples that Cory cites (SOPA, ACTA, TTP, DMCA, attacks on the Piratebay, mass reading of email, etc) orginate in the US and are foisted on other countries from there. While those countries deserve their fair share of blame for allowing a foreign power to bully them into this stuff, it is pretty clear where the problem lies. With or without nerds involved.
Either we fix the completely broken US political system (and good luck with that!) or the rest of the world needs to get better at ignoring absurd US laws and treaties cobbled together by lobbyists of private for-profit organisations. Neither those corporations nor general US politics concern themselves with the interests of the inhabitants of the rest of the planet. And the rest of the planet should respond accordingly.
Nerds (aka the tech community) can provide some tools to help out with that, as the Free Software movement and Wikileaks have shown.
