I dont know if Im more outgoing one way or the other...I sometimes find it easier to say things on a forum because I get time to think them out before typing....I also find it easier to be outgoing in person sometimes because things like facial expressions and tone count...
I'm pretty shy in person, but my job frequently requires me to be outgoing.
I'm a writer by profession, so I find it easier to express my opinion and share my thoughts in writing here.
