Disclosure
Duke: Two thirds of Buttondown revenue comes from flat SaaS tiers
“It's around two thirds comes from that flat SaaS revenue. The flat revenue is sort of the paywall for some of the premium features like custom domains, advanced analytics, that sort of thing. Whereas metered is purely based on volume. So only a third of button…”

Opinion
Duke: Hacker News launches are hit-or-miss 'lightning in a bottle'
“I think it's more lightning in a bottle. It's, there's been a plethora of people writing about, like, how to launch on all of these news platforms, and I do think a lot of it is very hit or miss. Like, sometimes you win the lottery.”
Justin Duke Aug 23, 2020 ▶ 9:34
Assertion Not checkable as stated
Duke: Months-old Hacker News comments drive substantial Buttondown traffic
“And I still see a large proportion of my traffic coming from, you know, comments that I've made months ago on Hacker News, as long as the content is relevant and the tool itself is put into the discussion.”

Insight
Duke: Product Hunt drives launch spikes but lacks long-tail traffic
“Product hunt is much more friendly in terms of letting people kind of glom on and being very sort of positive, like the community there in general is nicer, but it's the opposite of a long tail, right? Like you're not going to be able to bring it up in a lot o…”
