This is interesting to me too, because I have always used one identity online as well. I’ve been part of a lot of communities over the years but have always used some variation of my real name. I always attributed that to lack of creativity more than a desire to be transparent though 🙂

I think these online communities are an interesting way for young people to experiment with different identities and learn how to express themselves. I sure wish it was around when I was a teenager.
