I think about this often and have enjoyed being a guest on EGP, Slam Tilt, and the folks who stop by the museum to do news bits/etc. However, as Frax correctly identified, RPM and the B&B project keep my throttle to the absolute max. I don't want to start something I can't devote 100% of my energy to. It's frustrating. Tons of cool ideas... just no time.
In 2020 or perhaps 2021, I plan to greatly expand my YouTube site (Nic's Amazing Pinball Channel) which at the moment isn't quite so amazing. EM reviews, photos, art, and "recommended tweaks" will be made. A lot of effort will be put into good production quality and editing. I will use my personal machines at first and then expand to covering others (yours!) during my future travels and interview y'all too.
In the meantime, Mr. Baldridge has contributed a ton of content and if anyone else wants to give it a go, I'd be all ears. But keep in mind we are in the Age Of Snippets... and thus keeping it tight and topical will likely get better results (more episodes w/tighter focus vs. fewer longform discussions spanning numerous topics).
