Hey man, I just saw your Astro site in the Issues section of their repository and as every curious developer I had to take a look. ๐ Nice site indeed but I noticed that the links for the "Edit post on GitHub" are broken due to a trailing slash of the post's URL.
I will be posting a PR for this issue. ๐
Sidenote: the "Discuss on Twitter" is broken as well and it contains a TODO comment, i.e. https://mobile.twitter.com/search?q=%2FTODO-blogPostUrl.
