I'm not sure the opportunity costs are that high... especially when you're 1. Only spending a handful of hours on it (his claim) and 2. Your whole schtick for your consulting services is how you deserve $$$$ because using your A/B optimization whatever skills you can improve conversion/traction by xxxx%!
He spent 9 years on BCC that resulted in ~30K (edited, misread as 60K) in ARR.
I think his ideas and insights are valid. I just find it odd the contrast between his curated HN celebrity image as an uber-hacker with his actual results.
Doesn't seem like his skills resulted in much success with BCC but it sure helps his consulting career...
Sorry I'm the awkward guy at the party that makes people feel uncomfortable :)
