I agree GrinAndTonic
I think what is happening now is that regular longstanding posters are name changing so often that confusions like this will eventually stop happening because no-one will have a fucking clue who anyone else is anyway.
I had the same user name for years and now I NC constantly. I have about 12 atm that I switch back and forth from practically on a weekly basis. None of them have a persona attached to them really, because I don't stick with any of them for long enough at one time to get 'known.'
I like it this way. There is less grief and fewer crossed wires. I don't get that warm fuzzy feeling of being in a clique and getting name checked any more but very few of my old muckers are still here anyway, or if they still here they are they are incognito, like me. I really don't mind it. Since MN became so huge it's got less funny, less clever and more downmarket. It suits me to be completely anonymous now.
