"Most important reason": It's an insane deal for the price. I would recommend it to anyone with half a brain. I'm currently unemployed, and from a country that's not doing so well, but I wasn't left out, and that's awesome.
I have feedback though. Maybe it was me, but the talks were hard to follow with the chats. For example, I was reading Jason's answers in the channel and I could not pay attention to Matt's talk. Not a big deal because we'll have the videos, but the schedule was a bit compressed in time. It was a bit tiresome at the end, too.
But, I had a ton of fun, I learned things, I got the opportunity to chat with some of my idols, and I felt like a VIP all the time. Here's to next year!
