internet - Blogs: 4.5 million tools for the elderly

I have been scanning the Guo Liang survey for some details on weblogs. Based on his survey I can estimate the number of regularly maintained blogs in China on about 4.5 million. The survey says that 3.1 and 1.4 percent of the respondents keep their weblog 'often' or 'always'; on 100 million internet users that would be about 4.5 million.
The more troublesome statistic comes from the age group involved: mainly for those between 45 and 65 years old the weblogs are a popular tool. In absolute number those between 16 and 24 years old might still have more weblogs, but only as a percentage it is only half of the older internet users.
