Irrepressible
You might have noticed the small banner ad in the right hand-column. This is a little bit of Javascript that links to Amnesty International’s Irrepressible campaign home page.
The general idea is to support efforts against Internet censorship by spreading politically censored content as widely as possible, making it impossible to block. I had a similar idea a while back about creating a “poison pill” that would force the Chinese government to block large numbers of web sites, thus making the “great firewall” a self-imposed denial of service attack.
