Web3, DAOs, Blockchain — Help!

This is my first DAO. What do I need to know?

Is there any sort of financial investment? Do I need to have crypto? Or a crypto wallet?

I don’t really understand blockchain/web3, does that matter?

Web3 communities tend to feel a little cult-y or bro-y. What’s the vibe like?

Do we chat about NFTs and just like web3 all the time?
