I haven't read all 5 pages of suggestions, so perhaps these have all been suggested previously.
1. Write a Hugelkultur article for Mother Earth News. MEN, is more advertising-driven now than it used to be, but it is still the first back-to-the-land type read that most people see.
2. Hell, write an article for any magazine that has garden content. Real Simple, Martha Stewart Living, whatever. It'll be considered a "quaint" way to eco-up your garden. Doesn't matter to us if they view us as quaint as long as they're helping to spread the word.
3. There needs to be a concise and pretty Hugelkultur book with all the details, around 200 pgs and available for $20 or less. I know we have a lot of the info in Sepp Holtzer's Permaculture, but for the message to succeed it needs it's own book on the lines of The Humanure Handbook or Becky Bee's The Cob Builder's Handbook.
4. You're a Reddit user moreso than a Twitter user, but try to get some Twitter word of mouth going with a #hugelkultur hashtag.
5. Get 100 people to pledge to put in a Hugelkultur bed in 2012. People naturally talk about the projects they're working on.
Good luck!
