@fabionatali that would be cool; my proof of concept uses guile haunt (which should be what the guix homepage is using as well iirc) plus a simple script on top that runs in a cronjob. I think it could be integrated rather easily in the official website, even though commiting the reports each week will probably be a manual task.

The summaries currently look like this: https://me.literatelisp.eu/this-week-in-guix.html (if you'd like to have a look, uploaded july and august as an example to get the gist of it a few moments ago).

Another idea could be, to also include links to blog posts and interesting threads from guix-devel in it; but that would be more of a community effort as it would require way more resources in maintenance and curation than a automatically generated summary on what's updated/new in terms of packages.
