I'm (almost) the same (and don't think about Internet as "not real" but as a mean to communicate with other people more easily/quickly. Internet is still "IRL").
Though, I don't know anybody outside internet and don't talk to new/unknown people easily or by myself. Like The catboy said, it's easier with internet, but I'm still shy and don't go talk to other people I don't know, even on internet.
Maybe with other people (like at my work) I'm more thinking that I'm better than them and I know better than them.
I like when people are doing things like me for computer related things, because I know it works well and it's efficient
They are usually not trying to learn or understand, so it's frustrating. I may be more patient on internet.
While on internet I know there are people far better than me, I'm more open and accept every ideas (each his own).
Sometime I'm thinking my personality is more real on internet than outside. I'm shy and acting more cautiously, like smiling and acting friendly when I don't want to, with other people I don't care, etc.
On internet I can be active only when I want to, and talk more freely about any subject.
