Hello. I created the site. I think it can be useful to browse domains for certain sites. For example, Github.com can be used to browse popular projects. aws.amazon.com can be browsed to keep up with large AWS announcements, and www.reddit.com can be used to see top posts on reddit.
example: https://hntrending.com/domains/year/github.com/
Why did I create this site? Because it can be very difficult to keep up with tech news. There are great new stories on HN every single day. I simply can't keep up. The solution? A way to browse top stories from the past week/month/year or all time. I am letting the wisdom of the crowds decide for me what is most important, but it is nice to be able to take a vacation without worrying I will miss something big. I still read HN and other tech sites almost daily, but this helps me review the more popular stories which can be both interesting and fun.
