Hello - I created the site. I would encourage you to take a look at the 'links' section which is something you probably have not seen before. It aggregates and comment urls and ranks by count for a variety of sites - including XKCD!:

https://hntrending.com/links/all/xkcd/index.html

You can view summaries of Wikipedia articles or abstracts of arXiv papers on the site as well.

I hope you find it useful!
