Hi Rachel or should that be goodbye?
Anyway, I can understand why you feel that your two worlds are colliding. As far as I'm aware, no one else here has admitted to having an occupation that's so in the public eye.
However I would hazard a guess that, as you say, the sense of anonimity that the rest of us enjoy to talk freely about whatever problems we have etc varies hugely from person to person. Every time I see a board asking me about where I work, how I chose my nick name, where I live, etc etc I really enjoy answering and reading what others have posted, yet I know that the more details I give out, the easier it would be for some logged-on acquaintance, old enemy or colleague to spot me. Even when you're posting something that is totally mum-orientated and state the ages of your children or what nappies you buy, you are still giving out facts. I'm sure no-one would want to trawl through my messages and collate them, but if they did they could build up quite a detailed picture. So I do try to think twice before I put down details, while consoling myself that my life is so mundame there's little that's of interest anyway.
To be frank (now there's a good new nickname for you, Rachel!)I did think about inventing an extra 'virtual' child to add to our family to act as a smokescreen, but somehow I just couldn't do it. It would have felt too dishonest.
And then of course, even if you don't reveal your nickname, do you tell your partner about mumsnet or can they find out? Not a problem for me since we do not have internet access at home (there you go - another detail to chip away at my anonimity!). And in years to come, will my sons log on here out of curiosity and recognise themselves?
Sorry I'm rambling, I'm sure you're not as naive to think that all of us feel totally anonymous here, though obviously I can't speak for anyone but myself on this. I feel much, much, more anonymous here that with a bunch of 'real' friends, but I suppose you try to make a happy compromise - I have anyway.
