I'm wondering a little about potential strategies for the Peeragogy project. My impression is that the Peeragogy project as some sort of entity/group/organization is the main steward/driver for the theory, methodology and is one of the publishers of the handbook (if nobody else does, it's the job/mission of this project to keep it available and up-to-date as a resource). Sure, any peer can branch/fork off (benefit of customization versus benefit of collaboration/contributions) at any time and this group may even help with such endeavors as part of the broader peeragogical space. However, as one can learn from what's written in the handbook, peeragogy is not just an abstract concept, but describes pretty concrete practices. Therefore, with the preparations for handbook version 4, the reading group, working on book production and the content, aren't these meta-activities for the methodology, while there's the other realm of peeragogical practice that needs work too?
From what I've heard so far, several peers have projects of their own which may deserve registration, analysis, review/evaluation/suggestions/feedback, support and development (crowdsourcing, swarming a different one each month or something) in the Accelerator. Planet Math, Independent Publishers of New England and Uncertainty Principle as a few examples and maybe more I'm not aware of yet. Furthermore, what about an ongoing series of online teaching/co-learning, where any peer could request or offer a topic she/he is interested in teaching or learning, so others could "vote" or join these not just as limited events, but to collect and maintain resources + capacity so others can quickly pick up on the theme and get an introduction, mostly done too as libre-licensed OER (Open Educational Resources) maybe contributing/using Wikibooks or similar existing resources (no need to do everything from scratch)?
Activities like these could be organized in workgroups, one of which could be the technical/IT/data "department"/capacity
another one could be onboarding
to help newcomers to get an overview, register their interests/skills, point them towards the spots they're interested in + offering some handholding, if needed. The "Workscape" chapter lists functions that should be available to a project team, Sam Hahn too has his "9 Artifacts":
For each work group, we may ask and register which tools plug into these slots of the pattern/template, so it becomes easier for each project to get an overview of what's going on and how/where to join/contribute. Some of this may require technical tooling, but there's also plenty of opportunities for curation and content/data work for people who might want to help by filling some of the other roles, and the Peeragogy project itself could reflect and observe these practices on the meta-level to develop the theory and methodology.
In the field of (libre-freely licensed) software development, approaches like the one described above is established for a very long time now (despite the social features aren't necessarily developed well), but less digital domains could make use of peer principles found there, be it for learning/teaching, publishing, media literacy, software tools or other topics. It would be relatively important to maintain some sort of neutrality in order to avoid that one party manages to accumulate unjust privileges over the other peers, but this shouldn't be too difficult given the good and bad examples we can learn from. For example, all data should be open data regardless of what tool is used, so others can make independent use of it, for which subsequently libre-freely licensed tools should be made available and maintained as well.
For non-software-development online collaboration groups, consider the Digital Life Collective:
Their thing is a paid membership for investing into the development and integration of tools (from a members perspective, probably mostly renting the hosting, service and software), so members get access granted to a platform of Mattermost and Federated Wiki instances (and whatever else might get integrated into their platform), also with graph and holon visualizations of projects and activities. Robert Best builds the Open Learning Commons
which in part uses libre-free licenses for some of the published/public learning content/discussions, but the OLC seems to be more on the learning and less on the workgroups side. There are likely similar communities, it might be worth collecting and reviewing them because why start another one from scratch, if there's the option to collaborate or cooperate with an already existing one, or at least learn their good parts and avoid the bad parts.
Douglas Engelbart proposed the ABC model for strategic, systemic, exponential improvement:
which I find highly relevant here. Helping others with what they want to do towards the common good helps them with helping you again, for the pile of good material becoming even better which then attracts more people to make it even better again.
Full disclosure: I personally don't have enough time/capacity/skill and not even too much of interest in building all the stuff that would be needed, but I do believe that a lot of little steps accumulate and working together and collaborating could easily compensate/exceed individual capacity shortages, especially if invested wisely into the strategic meta-improvement that saves everybody from manual or pointless tasks where computers and digital are there to enable new, much better ways to do things, if used properly and for realizing its full potential in our service.
