So Steve and I are obviously open here about who we are in 'real' life, and I share things here that I wouldn't elsewhere, not things that would get me in trouble really, but things that are just more than people need to know.
The only time I have that panic is when I tell a story about one of my internet friends (an it comes up kind of a lot, what with all the PJ people, and the people here, all the *-cons I went too, all the IRC chats, and tiny chats, and impromptu meet ups...) If the person is not familiar with the concept of having internet friends, and asks how I could know all these people from all over the world...
Oh they are my internet friends, I met them online.
Online where? How do you just meet people online?
Eerrrr, a forum linked to a webcomic.
OOO which one?
And I refuse to tell them. There is nothing I wouldn't be comfortable owning if it came to light, but I think relationships are built on an equal sharing of information, and I am not comfortable with someone I have been on a few dates with, or a class mate having access to years of my posts here when I know nothing about them.
