I worked with Andrew for a while, and I can confidently say that he's a good and smart product guy. He had a good vision for the future of Groupon. Things obviously didn't work out, but it will be ignorant to put all the blame on him.

This one time, a business school professor interviewing him in front of a lot of MBAs asked, "So, what suggestions do you have for a student who has a tech startup idea, and they need help finding developers to build the first version?" I'm sure she was expecting him to talk about finding contractors, interns or free CS students . His response: "Learn to code." Since then, I've always felt he was one of us.

Many of us would have done exactly what he did (or maybe worse) if we were in his shoes (inexperienced entrepreneur running the fastest growing company ever, where everyone around him had a lot more weight).
