Actually I think this is a great idea! It's funny how you mentioned this idea, as I am in the exact same process of wanting to do the same type of Developer Commentary/ Post-Mortem Content for my own indie games. I'm currently in the same situation, I'm starting out as an Indie Dev, and I figured the documenting of the process of each individual project would help me out a lot, and be entertaining to watch and help other Indie Devs starting out. I just finished my first small game, and after that I finished another project for a small game jam, and will be uploading Developer Commentaries within a few days.
I would definitely watch, as it would also help my ability as a Indie, and since I'm doing something similar we could easily learn from each other. If you ever decide to upload a video send me a PM or something and I'll give it a watch! The type of peer-to-peer educational is invaluable in the Indie Game Community.
Indies just seem to be reclusive at times, don't be afraid to share!
