It's got me thinking ,sparky - I wouldn't post under my real name because I'm quite a quiet private person in RL (I'm quiet here too!),and I was thinking that it would feel odd to me that someone I didn't know well could come here,read my posts,and they'd know things then that they wouldn't have learnt from me in RL because we didn't know each other well enough...
It is different talking to people anonomously on the internet.
But thinking a bit more it isn't as if I would mind what people thought about most of what I post - and it might make RL more interesting!I think your way of being as open as you can be might be better.
I would feel differently about an employer being able to search and read my thoughts though.
I'd namechange if I had something going on in my life which I desparately needed to talk to someone about,but which in RL would then mean that whoever you'd discussed it with would know about it forever,whatever happened,and here might mean you'd be associated with it forevermore,some sex and relationship stuff for example.
I don't think it is oppression - I agree with Elephants,I think it gives freedom from being judged on face/clothes/accent etc
Have I just contradicted myself?!
