I've never met anyone from ZD, no. I'm not very big on meeting people from Internet, I've been asked and had to kind of politely say no because I didn't feel too comfortable doing it. I've met a few but only after I've known them a long long time, like from LoZ.com since I've known some people there for, what, 8 or so years. I actually stayed with one of them when I was down in London and he showed me cool stuff, like this store where when you go downstairs there's tonnes of computers and there's huge LAN parties! And a friend was visiting a local University so I travelled to meet her and show her around. And I've met some people from NeoGAF when we went to PAX, and everyone booked up in the same hotel. Was brilliant.
But no, never met anyone on ZD.
I've only been back a little while though.
