A couple of weeks ago, I can across a website that searched sites like Hacker News and Lobste.rs for comments on an article. I thought I bookmarked it, but I can't find it. Does anyone know what I'm talking about?
<a href="https://syften.com/" rel="nofollow">https://syften.com/</a> searches for comments, but you have to supply a search term (not URL).
