I've been to Mashup Camp, ETech and MIX in the past month and a half. So has Kaliya, otherwise known as Identity Woman. She calls MS out for a http://www.identitywoman.net/?p=296 as well as the lack of an official wiki for the event. She's right on both counts. I thought some of the logistics of ETech were suspect, but they sure did assume that every single attendee would need power and laid out power strips accordingly.
I kept seeing Kaliya at these events, but I didn't get to meet her until she came to the SPARK @ MIX session Monday afternoon. She's one of the organizers of the Internet Identity Workshop. Sounds like a cool event, but it's right before my daughter Rileyanne's first birthday and you know Jules would NEVER forgive me for missing that.
