I wrote about this recently in post about future startup ideas [1]. Go is young and building an IDE along with its evolution would be amazing. LightTable might be very successful with that, but I imagine the more exciting place for Go IDE experiments could be Android and tablets. As multicore mobile takes over, I think a few years out apps in Go might be a popular thing; and building software on the target platform hasn't happened much with mobile yet. AIDE [2] is really really amazing, but it's not quite the revolution that I'm looking for. I'm quite excited for where this goes.
