Breakdown of the Blogging Community

Intac has a cool graphic on the breakdown of the blogging community. Not surprisingly, men make up 2/3rds of the community. Only 35% say they are professional journalists; I am kinda surprised by that number. My first thought was that it would be higher. 27% blog 3-4 times a week and 50% spend less than 3 hours actually blogging. I actually thought the number would be higher here too. the again, a majority of the blogs I read do supplement (or get all of) their income from their blogs. What do you think? Did their numbers surprise you?
