I once predicted in 2006 that Baidu might launch email and IM services (遗憾 that I didn't write it down at the time, so I can't find any evidence of me saying this). I thought that Baidu should launch the email service first, and then the IM. Last year, Baidu announced with great fanfare that it would launch C2C services this year, but unexpectedly, the IM was launched first!
