My name is Jenny. This is not an alias, and I'm perfectly fine with using my own name. I use it often. I trust a lot of people on the internet with my personal information. Im friends with a lot of denizens on fb.
However, i dont think any of them know my address. They could, I'm sure, but I know who I friend. I make sure theres a life behind the profile.
In the end, i believe in the right of it. But its a power that has to be wielded carefully. Trust wisely.
