I really like the Permaculture Activist, it's a
permie magazine for the U.S. and often has articles by people you'll meet in the permaculture movement, and more locally based (or north carolina based, but closer than UK). They also tell you what topics/issues are coming up so that people can contribute to the topic.
The
Permaculture Magazine is nice, but it's based in the U.K., so I get more out of reading the Activist.
and then there's some even more
local fun stuff that is often in a good permaculturist's kitchen. Yes magazine, and Seattle Tilth newsletter, to name a few.
