definitely chatrooms... I like being a part of a larger whole, with my individual identity being mostly irrelevant.
That way I'm never really noticed, which is very freeing.
I find it interesting the responses in chatroom ppl feeling they can be more unnoticed if they want to be. Which is true, you can hold back whenever with far less pressure.
I like being part of the whole in the chatroom; I think my individual identity becomes more clarified. I notice that with others too, I notice by being part of the "community" in a group their individual identity's are more pronounced, in a good way.
