I dont think I have changed at all. I'd hate to come across as agressive as thats not in my nature. Well, no -one picked on me yet so will have to wait to find out. lol.
I've changed loads. AB was the first social site I had ever used so I was a bit childish :-) Also my life is completely different now so I've mellowed for that reason.
I don't feel as though I have, but I suppose over 9 years one must have evolved in some way (he says hopefully) that differs from our first utterances.
I would say I am more impatient these days, perhaps reflected in shorter blunter posts - and my typing has deteriated leading to bad spelling and grammar.
