I've been going to US tech conferences yearly in the last few years. As of 2016 this has stopped, since the fact that I was snowboarding in Iran in 2011 now means I can't get a visa through ESTA. I now have to take a day off work, fly to Oslo, talk to someone at the US embassy, in order to get a visa. It's just not worth the effort at that point.
