Today, someone that I didn’t know added me to their IM list. I assumed that it was a work contact. But, no. The stranger claimed to be from China, and the domain of his e-mail address more or less confirmed location (I checked WHOIS).
At first, I thought this person might have sought me out. I have been recently quoted in a Chinese newspaper and on Western news services, about Google’s Chinese research facility and, separately, Google, Microsoft and Yahoo! agreeing to censor search results in China. The IM looks to have been random, though.
