GNU Guix has a good blog, but I don't feel like they are very "marketing" focused.
It's hard to describe precisely, but a lot of free software projects do a good job of putting themselves out there in an unfussy way. There really is something refreshing and cozy about that.
i think this is especially true of projects run by people with deep experience in the field and are in it “for the love of the game”, and don’t feel the need to stunt on everyone in hopes that they are taken seriously.
