I like it, but it's not reliable, as I've been going through "The Hacker Classics" and the comments section is not coming up.

Should show this https://news.ycombinator.com/item?id=16442888 right?

Yeah it should. There is a slight url mismatch in this particular case. The HN Api response is returning the url without a trailing slash and hence my code is rejecting that result. I will try and fix it. This was just a basic version coded up in a few hours to see if people find this useful at all.

Woah a couple of hours? cool! It's great to find the hacker news discussion if I'm on a random webpage, I find it very useful :)

Yeah. It's just a single API call and few lines of javascript. I took more time to create screenshots and add descriptions on the chrome store than to code it. Even I find it useful personally and that's why I built it. But it doesn't seem to have piqued HN users' interest or maybe just didn't get enough visibility.

Could be the title, not sure how you could make it clearer though. Maybe something like this would entice people.
