I had a great time at Minecon this last weekend. To be honest, while Minecon itself was fairly fun and interesting, talking in person with people I've been chatting online with over the last two-plus years was the best part. I got to hang out with several other players from Minetown, including the server owner sawine (as cool a guy in person as across the internet :) ). Several of us had dinner on Friday, socialized at sawine's hotel room each night, handed out masses of Minetown stickers, and just generally hung out as a group or in mini-groups throughout the whole event.
Admittedly, I didn't end up taking out the camera as much as I probably could have. Was busy just enjoying being there. :p
