Great Firewall of China : Use this tool to find out if your site or blog is banned in China. WeblogToolsCollection is not. It is interesting to notice that the disclaimer states that some sites might simply not be available for techincal reasons which might have nothing to do with censorship. Some of the obvious culprits that I tried came back with mixed results. Source: Various WordPress.com blogs that seem to be blocked.
This is also a good time to mention that I am going to be visiting various cities in China and Japan at the beginning of December including Shanghai, Beijing and Tokyo and would love to meetup and exchange ideas and contacts with my readers and other WordPress users and bloggers while I am there. I will be posting dates soon.
