Comments: Why do teens feel that when they blog it has to be written like if they are talking to a bunch of their friends in the school hallway?
Teens these days care little about their intellectual impressions. I doubt they are mature enough to even be aware of it. A teen aged 14 of 40 years ago was equal the maturity of a 19 year old now.
I believe blogging for teens can be a bit different for them than it is for adults. When an adult blogs they usually do it with a particular subject in mind and for a specific purpose. Teens on the other hand may be doing it for a release from the stresses of being a teen.
