To those who suggest women don't blog --- and that's an old assumption, mind you --- Sysomos notes that 50.9% of the posts came from women.
To those who believe older people are big bloggers --- and that's a new assumption --- Sysomos notes that 53.3% of the posts came from those 21-35 and 20.2% from those 20 younger. Only about 7 per cent came from those over 50.
More than 29% of blogs emanate from the United States, by far the largest national contributor to the sphere.
