What is the offer mentioned in the item title. 'Offer HN'. Sorry to be negative but I'm not sure a podcast counts as an offer. Disclaimer: Haven't listened to the whole podcast. Not based in the US so not interested in US specific law knowledge.
Most people feel obligated to incorporate to have a "real business" when it's usually unnecessary. If you still have questions after listening to the podcast, I'm offer my help to answer those questions and to provide further guidance in the process.
