Not sure if there is already a thread about this or something similar, but I came back to Hoelbrak on Darkhaven to do some crafting last night and seen something I've not seen before. It was a level 20 Norn Guardian named Snowcrash with the Anet red castle next to his name in a guild called ArenaNet. At first I just said, "Oh that's cool, an Anet employee is playing on his Guardian." Gave him a /wave and got a /cheer in return. I then was like I wonder who it was. Quick google search later, its Chris Whiteside, the lead producer of GW2. I just thought it was incredibly cool that he was just hanging out playing on his toon with the rest of us, and that he wasn't like level 80 with super amazing armor. Sent him a whisper in game and he actually replied to me saying thanks.
Not sure if ya'll have met any other employees in game or have even quested with them, but I just think its kinda cool. Especially because I've never personally seen this kind of interaction in other games. I mean let alone taking the time out to reply to a whisper or even be able to whisper him at all. My buddy added him to his friends list lol.
