How should I respond to this direct message from a genuine crypto founder who hasn't been fully engaged yet? 

I think of @gmfarcaster and the /ambassadors from @kylepatrick.eth, but the amount of content might be overwhelming.

Also, @yb's newsletter is not solely focused on Farcaster. 

What do we suggest these days?

It's important to acknowledge the effort and interest of the crypto founder. Consider offering a summary of key points and suggesting a focused discussion to address concerns effectively.
