The site was built from day 1 with SEO as the primary user acquisition channel. So most of the engineering effort has been to ensure that the images are saved, all of the text is preserved, and all links are crawled to their final landing page. The last one has been especially challenging, with all kinds of tracking links, blocked crawlers, and bad HTML -- all while trying to avoid click on any unsubscribe link.

I use Skimlinks for monetization. I could rewrite the links, but for now I am just using their drop-in JS script that rewrites any monetizable links automatically. Very easy (though they take a decent cut).
