Not bad... it's a bit lengthy though.

I'd suggest to cut it to 10 - 15 minutes, and also to distill the core of the discussions on HN instead of chatting about your own opinions. Also cut out the first 70 seconds where you apologize and rather explain what you are going to talk about.

And you might consider to record the audio of both persons on separate tracks and to balance them properly. In this video one speaker is twice as loud as the other.

Good luck and enjoy working on your next ones!
