Of the general population of online women who write blogs, 58% post entries at least weekly and of those who read blogs, 80% do so at least weekly - claims a recent study by BlogHer and Compass Partners (U.S.). Interestingly it's also at the cost of traditional media: some 24% of the women overall watch less TV and another 25% and 22% of the general consumers read fewer magazines and newspapers, respectively.
