Two routes, and I will be honest about which one works.
If you have my number, you already know how this works. Use it. This page is not for you and I would gently suggest you stop reading it.
Everyone else gets the form. You can fill it in and see what happens. I do read all of it, which is a different commitment from replying to all of it, and I would rather say that here than let you work it out from the silence.
Things that improve your odds considerably: being specific, being wrong about something in an interesting way, or having read one of the pieces and disagreeing with it. Things that do not: the word synergy, an attached deck, or an opening line that tells me you have been following my work for years.
The form
It opens a message in your own mail program. Nothing is sent to this website and nothing is stored here, which on a site about what happens to data after you give it away felt like the only defensible way to build it.
