My colleagues and I have been on this forum a fair few times (we work in the SEO department for a big company)... A few months ago my colleague was in the canteen getting some food, when he looked like he had seen a ghost. When we got back he said he had recognised someone from their avatar on Blackhat World! I dont think we properly believed him - until a few months later - the guy applied for an internal job in our department - and it turns out he really does go on BHW!! How freaky is that?!! What a small world!
