If you're looking for someone baring their 'true' souls to the world, how much more 'true' can you get than someone displaying their innermost fantasy personas to the world?

I think this was already answered before you asked it -- like what their name is, where they live, how many kids they have, etc. That's a lot more real than some persona somebody invented, which could have to do with some movie they saw, some incident in their childhood -- and could have very little to do with their actual personality.
