On the topic of gathering people, here is my experience:
Online communities didn't really work here. This isn't just my own, but also other's. People told me that it wasn't working very well.
Local communities seem to work much better. That's the case for me and that's what I've been told. These communities are mostly around self sufficiency. My aim (which has been similar to these other communities) was to make people join or start new local communities. I think there's a lack of trust in people in general and there is also an information sharing problem. There's too many channels/groups and too much information flowing everywhere. It seems that most people are more interested in (controversial) news rather than solutions. I suppose the lack of education around technologies is the real culprit. Technologies should not be used to replace real life social interaction. That is my stance so far. My conclusion is that online communities should be about working together to advance knowledge. There is already people working on open source science, there's the open source software movement that attract more and more people and of course, permies is a great collection of this online and real life team working.
As for sharing, my focus is more on storing data and sharing it than the marketing of it. Once the product (which is refined knowledge) is good
enough, it should share on its own. Although, I truly believe it will be shadowed somehow. At least, that seems to be the case for some open source oriented communities, they sometimes get attacked in some way. I wouldn't be surprise it would have been the case with Permies in the past (or even currently).
Anyway, I think we should focus on organising knowledge to make it more accessible. That would be the first topic I would put time into. It shouldn't be something time consuming, as this can easily become a problem to focus too much on how things are stored and presented to make people want to read it. I think it should be organised in a way that most important topics (like energy efficiency such as RMH) should start with doable steps to start without much hassle and then explore more if needed. Something along these lines. Maybe we should focus on gathering worthy data and give it to people who wants to organise it their own ways and present it.
I've already started gathering data on my own. I advise everyone to do so. Simply put a folder on your main computer that has some space and organise stuff however you want. Everything you find interesting online, save the page (there are extensions that collects html and images and put it on a file that can be stored), videos, your own experiments, etc. For people who are more interested in this data gathering, I could share some of the stuff I've done to make it more efficient.
That's it for me today. I hope this was clear enough. I still have lot of work to do before I can be more available for this. Thank you Leslie!
