I did one about "how to get
permaculture to be a household word" - I think that went out a few days ago.
I frequently encourage people to start blogs and make links to all stuff (not just
my stuff) that they think is good.
We have some ideas in the tinkering forum. But I have to admit, that I'm a bit stumped about reaching a much larger audience. Or maybe you are asking about how to share information at the level I have now reached - like how did I go from zero to this point?
Well, either way, I think the best thing is to ask questions in the tinkering forum - there is a
thread there for podcast questions. And when we fire up a podcast we turn to that thread.
