Knowable feels like something that should already exist, but the reality is before the team built it, it didn't! It's both technically well-built and stocked with useful/actionable tutorials. It's like Masterclass, only helpful and not untouchable, only audio not video, and affordable not obscenely overpriced! Ok it's not like Masterclass but you'll be asked if it is if you tell someone about it, so be prepared. :) Looking forward to delving deeper into the catalog!
