1) "Ylmf Windows XP" was a real pirated Microsoft product prior to the arrival of "Ylmf OS" which is Ubuntu Linux. The Ylmf team has been frightened away from distributing real Microsoft products by the arrest of the distributor of "Tomato Garden" which was also a real pirated Microsoft Windows XP.
2) http://www.XP.com/ points to Ylmf OS
This attracts a lot of people who are looking for XP to the Ylmf OS site.
3) Google trends shows that Ylmf OS has become a very popular search target in a short time:
So will there be massive increase in Chinese Linux users?
Will they adopt it or go on flouting the law using pirated Microsoft software and ending up in Chinese jails (which can't be pleasant.)
