On May 13th a Roast My Landing Page blog post trended on Hacker News.
The post, what I learnt roasting 200 landing pages in 12 months (http://blog.roastmylandingpage.com/landing-page-roasts/), remained on the Hacker News homepage for over 24 hours, generating 684 points and over 230 comments.
This lead to 40,000 blog visits and £10,000 in revenue in 48 hours.
