I'm looking for a Chrome extension that will show if a page I'm looking at online has been submitted to Hacker News. I'd like to be able to click on the notification and be taken to the HN submission/comments page to read the comments.

Is there anything like this?

For those of you with .io domain names, how do people in the "real world" (i.e., people who aren't very tech-savvy) respond to them? Have you gotten any positive or negative feedback? Any misunderstandings or confusion?
