Good to have more hard figures and particularly useful to have demographics. It’s interesting that the writer at Cyberatlas spins the story to make them seem more democratic. If it was me I would have used the same figures but said something like, “despite receiving quite a bit of media attention, only two percent of people who are online have created weblogs [does this include ones that are no longer active?] and these are heavily skewed towards a wealthy demographic – almost half have a household income greater than $60,000. According to this census report US median income in 2001 was $42,000.”
I was surprised that only 4 percent of the Internet-using population reads blogs, but if you consider that they tend to contain 1) personal stuff aimed at a circle of friends and family 2) political stuff at a level of detail most people don’t need or 3) technology-related stuff at a level of detail most people don’t need it becomes less surprising.
