I've met a few people off the net, particularly when I was with nzd.
I had some good experiences and some not so good experiences. I went to a couple of events which I didn't enjoy at all (due to bad behaviour of some attendees).
I have met some amazing friends though and am certainly glad to know them now. I also sort of met Kall via the net and that is definitely all good
I found the majority of people were quite like their net personas with only a few exceptions.
