XOXO is a truly remarkable festival and conference that you've heard me talk about quite a lot. I interviewed Andy Baio and Andy McMillan just before they announced the line-up for the 2013 show, which took place in mid-September. At XOXO, I interviewed the folks behind four companies or projects exhibiting there about what they were up to: Brewbot, Draplin Design, Projecteo, and NeoLucida.
