In China we ran into something we knew nothing about, informally known as the Great Firewall of China. We tried to access this blog from our laptop, but we couldn’t connect. Internet searches were slow. Wikipedia has a good article at http://en.wikipedia.org/wiki/Great_Firewall_of_China. With help, we were able to post to the blog from China using email, but we couldn’t view or edit what was posted. Blog access from Hong Kong worked.
Bloggers visiting China should prepare by setting up email posting in advance. We had read articles about companies cooperating with the Chinese government to limit information, but running into the Firewall made these limits more real.
