Welcome!
As a intro, I would check out the blue pill https://thebluepill.eth.link and how we think about Yearn. Also, you can find more info on our public notion page. Generally, the Yearn DAO is focused on improving, maintaining, and iterating/expanding on Yearn’s products.
Glad to hear you heard and liked @tracheopteryx talks! Feel free to reach out if you ever have any more questions.
