I initially was a little skeptical when I first read this, but I could see a monthly newsletter with a curated and concise roundup of the most important updates, changes and discussions for PyPA projects and the packaging ecosystem being a valuable resource, at least for PyPA project maintainers, packaging community members and other devs interested in keeping up to date on packaging. It’s also something I’d personally be pretty interested in both subscribing to and contributing to the editorial team, since it falls pretty squarely within my wheelhouse.
One caution, though—its very hard to see any kind of newsletter reaching or appealing much to the ≈95% of Python users who don’t already care about packaging—even with heavy promotion and tailoring it accordingly, it’s hard to see it reaching more than a tiny fraction of “regular” end users beyond those who already have some interest in packaging, or are in a particular position where they feel they need to stay updated on it.
However, IMO it isn’t the end of the world, as we can still have the news trickle down to those users indirectly so long as we can attract enough prominent community members, “go-to packaging people” for their org, and folks with enough time/interest in packaging to care somewhat even if not enough to follow all the discussions regularly. With that in mind, publishing should of course be on an existing (relatively) high-profile blog/website in addition to email, Discourse, etc., which gives those folks something to share with others, helps people come across it later, reduces the investment to skim it and allows third party content aggregators (Reddit, Hacker News, etc) to pick it up if there’s a particularly interesting item that captures wider attention.
NumFOCUS, perhaps the closest rough equivalent for scientific Python as the PyPA is for packaging, has a similar newsletter they send out giving the latest updates for NumFOCUS sponsored and affiliated projects (basically all the core packages in the scientific Python ecosystem, and lot more), where each project sends in a few bullet points plus NumFOCUS mentions any major happenings on their end as an organization.
It’s nice in theory, and we (Spyder) regularly contribute to it, but I’m not sure it’s really that useful or that many people actually read it regularly since there’s just way too many projects (usually several dozen each newsletter), only a handful of which any given user actually care about, and for which the updates vary in significance with little central editorial control.
To avoid this issue and be have a high value to time ratio for readers, such a newsletter should be reasonably selective about which projects and updates it includes, focusing on those which have a meaningful impact on a substantial number of users, and organizing them in a way that’s quick for the user to skim to just what’s relevant to them.
