Something to note, for those who want to flood nice people with emails: I sent him a couple emails (probably similarly stupid questions -- I recall one was about his thoughts on Twilio having a "build your own appointment reminder" page -- not a direct competitor for your customers, but that does seem a little rude, no?), and never got a response. Nice people get busy, and it's best to consider if clever googling / just trying it will be a better use of the shared public resource called 'Patrick's Good Will'. In my case, I could have just e.g. assumed his thoughts mirrored mine, because even if they didn't, not really important to me.
