Over at Outbrain, we are helping the victims in Japan by driving 1/4 million readers from the outbrain network to pages that inform people how they can help. So we'll be pointing links to non-profits such as Red Cross, Salvation Army, Save The Children and others.
You can contribute as well. If you see any web pages that inform folks how they can help, send the links to email@example.com and we'll get them loaded into the system. Links can also point to pages on other sites that list ways folks can help.
here's our blog post for more information.
