This is my new writing space. I have been posting to several other sites, mainly 'Artbasher' under the nom-de-plume William Blake. You may notice that in 'Blogger' the n-d-p has changed to Kim Finn-arty, this was mainly to keep one step ahead of other blogger posters who refuted pen names. Anonymity is a handy too in the tiny NZ art scene; because they are all petty, backstabbing bastards. Try saying that with your real name appended; even if it is the truth.
The n-d-p is also quite handy when dissing your mates, roasting your dealer or bemoaning the discounts that collectors can demand. There is also the twisty issue of tacky self promotion.
So the anonymity is a life preserver for the man going overboard.
