No big surprises in there, but it was a great interview, very professional and circumspect, and gave a positive impression. I had sort of surmised all of the answers that were verified by the interview. Was hoping for more clarification on the MIR issue, but he's probably right that it's too early to stake out a position one way or the other. I know Xubuntu & Kubuntu 14.04 LTS won't be using MIR. I'm pretty happy so far with Xubuntu 13.10, but was not so happy with Kubuntu 13.10, which had a lot of problems relating to the updater, at least on my rig. I liked the insight he gave into the reasons behind pursuing LMDE. I think it's a good idea to have a Debian-based version. He's hedging his bets against any Ubuntu wackiness in the future. Indeed, that may be the way that Linux Mint goes in the future. I think it's an indication of wariness, caution, uncertainty regarding the future direction of Ubuntu, and it does seem justified, but there is no need for commitment to any one path just yet.
