The solution: use the server as little as necessary, do as much as you can on your device.
Use Git.
Version control, yes, but more importantly, already optimized for p2p and sneakernet.
It allows for collaboration.
You can take a project someone else started, and finish it.
There's already a whole bunch of gui programs available on all major operating systems to track and manage repositories, nothing needs to be built to start. It's ready to go.
Most people are hosting their repo on some Git forge already, you can track it down, or maybe more people can start sharing the url to clone the repo.
Git does have size limitations: so you need to break up bigger projects.
And even before you get to those, in order to make it easier to clone, keeping projects small and modular helps keep things manageable.
You're already doing cool stuff, just start sharing it with Git; and RSS, ATOM, siloed social networks, and unwieldy Wordpress blogs become an unecessary relic of a more fragile past.
