The Wall St Journal has an interesting article today on people who blog for money. According to the lead, 452,000 people claim that blogging is their primary source of income:
Demographically, bloggers are extremely well educated: three out of every four are college graduates. Most are white males reporting above-average incomes. One out of three young people reports blogging, but bloggers who do it for a living successfully are 2% of bloggers overall. It takes about 100,000 unique visitors a month to generate an income of $75,000 a year. Bloggers can get $75 to $200 for a good post, and some even serve as “spokesbloggers” — paid by advertisers to blog about products.
This is a lot higher than I would have though this number should be but it suspect it also includes those who blog corporately or blog for high profile sites like Huffington Post.
